Ongoing Sec – More Exploited Vulnerabilities Patched

29 December – Krebs reports that real bad guys are breaking into Microsoft Windows computers using a newly discovered vulnerability in Internet Explorer. Now we know what a “Watering Hole Attack” is – the targeted compromise of legitimate websites thought to be of interest to or frequented by end users who belong to organizations that attackers wish to infiltrate.

 

Being fully upgraded does not stop this exploit~!

7 November – More Mandatory Flash updates; Best explained at Adobe Ships Election Day Security Update for Flash — Krebs on Security, who warns, “Adobe urges users to grab the latest updates from its Flash Player Download Center, but that option pushes junk add-ons like McAfee VirusScan. Instead, download the appropriate version for your system from Adobe’s Flash Player Distribution page. Most users can find out what version of Flash they have installed by visiting this link.”, then goes on to explain with graphs and links the best things to do.

Flame – oversights and expertise made for Windows Update worst case scenario

Windows Update compromised


5 June – Flame and Windows; at one time it seemed like Flame was going to be a real lesson, and it would be a non-event. Just a virus/trojan package that has been around for a few years, hitting ‘those guys’ in the middle-east somewhere. Now it turns out that hundreds of thousands of people are affected and have been for a long while, and that it was signed by a Microsoft SSL Certificate and the only thing certain is that there are more surprises ahead.

Then today Microsoft says they have a solution, download an update today. Oops, another news story says that the hackers have performed a “man in the middle attack” that allows them to infiltrate your computer when you think that you are getting a real Microsoft Software Update.

The answer is that you must have your employees upgrade their Windows software. Read the stories yourself:

9 May – “I just went through several days of hell after Microsoft’s truly massive Patch Tuesday updates trying to fix my Adobe PremierePro CS5 edit system, only to discover that Nvidia released an update to ALL the Quadro cards on May 4 that is required in order for ActiveX to work properly after the Patch Tuesday events.” Robin McCain reports at Cutter-Talk. “This may or may not affect Mac owners who use Quadro cards for editing, but it is worth checking out if you suddenly have problems…”

Meeanwhile, Apple pushes on with several security fixes in a 350MB  10.7.4 upgrade…and a similar upgrade for 10.6 users. Use the Software Update pull down. Here is the Security Issue:

About the security content of OS X Lion v10.7.4 and Security Update 2012-002


15 April – Use the standard Apple Software Update pulldown now because: “This Java security update removes the most common variants of the Flashback malware.

This update also configures the Java web plug-in to disable the automatic execution of Java applets. Users may re-enable automatic execution of Java applets using the Java Preferences application. If the Java web plug-in detects that no applets have been run for an extended period of time it will again disable Java applets.” About Java for OS X Lion 2012-003


10 April – “What makes this bulletin stand out is that Microsoft is aware of attacks in the wild against it and it affects an unsually wide-range of Microsoft products, including Office 2003 through 2010 on Windows, SQL Server 2000 through 2008 R2, BizTalk Server 2002, Commerce Server 2002 through 2009 R2, Visual FoxPro 8 and Visual Basic 6 Runtime,” Kandek said. “Attackers have been embedding the exploit for the underlying vulnerability (CVE-2012-0158) into an RTF document and enticing the target into opening the file, most commonly by attaching it to an e-mail. Another possible vector is through web browsing, but the component can potentially be attacked through any of the mentioned applications.”

Other notable fixes from Microsoft this month include a .NET update, and a patch for at least five Internet Explorer flaws. Patches are available for all supported versions of Windows, and available through Windows Update.

16 Feb – The exploit seems to affect IE users on Windows at this time, but Adobe is telling everyone to go to the Adobe Flash Player Download Center and get the latest inoculation. Krebs says (Flash Player Update Nixes Zero-Day Flaw — Krebs on Security):

“…although if you’re not careful to untick the check box next to whatever “optional” goodies Adobe tries to bundle with Flash Player (the most common is McAfee Security Scan Plus) you could end up with more than you wanted.”


14 Feb – Patch Tuesday…but don’t update Silverlight…jeesh.

Force an update on your iOS Skype, as they have repaired a flaw that could expose your contact list, among other things.

Last week, Mac Trojan hunters found what appears to be a proof-of-concept use of a malware program for the Mac hidden inside a PDF. Open the PDF and the other program opens in the background. Today Apple has added that to their super list of Super Don’t Open XProtect malware signature list. Great, if you are using 10.5 or above.

But this might be a perfect time to bring up the question, “Why is anyone in need of security using a PDF file that isn’t secure. The only secure PDF file is a PDF/A file, also known as standards called ISO 19005-1 and ISO 15930-3 – that’s PDF/A-1 and PDF/X-3. It appears that we are entering the age of darkness.

KNOW AND TELL OTHERS THIS ! ! ! – This particular upgrade is not ready yet for OS 10.5 or below. Also, it does not protect against infections through USB drives, BitTorrent downloads and other similar methods of penetration. This is not going to be the last that Mac users hear of this.


Apple releases update to protect against MacDefender | Naked Security says:

My impressions? A good reaction from Apple in a short amount of time. They are making the best of what is available in the OS X platform at this time. Unfortunately it falls short in many respects.

The biggest problem is the lack of an on-access scanning component. While LSQuarantine works to protect against downloads in most browsers, it doesn’t prevent infections through USB drives, BitTorrent downloads and other applications.

Daily updates are a good start, but it remains to be seen how frequently the criminals may release new variants. If they start moving in a polymorphic direction similar to the one the Windows malware writers have gone, XProtect will have issues.

Of course this update only applies to OS X 10.6 “Snow Leopard,” so older Mac users are left unprotected.

OS X 10.6 users should apply this update as soon as possible, and I recommend installing a more fully featured anti-virus solution like our freeSophos Anti-Virus for Mac Home Edition. It’s totally free; we don’t even ask you for your name or email.

Adobe: Attacks on Flash Player Flaw — Krebs on Security

“Adobe warned today attackers are exploiting a previously unknown security flaw in all supported versions of its Flash Player software. The company said the same vulnerability exists in Adobe Reader and Acrobat, but that it hasn’t yet seen attacks targeting the flaw in those programs.

In an advisory released today, Adobe said malicious hackers were exploiting a critical security hole in Flash (up to and including the latest version of Flash. The software maker warned the vulnerability also exists in Adobe Flash player 10.2.152.33 and earlier versions for WindowsMacLinux and Solaris operating systems (10.2.154.13 and earlier for Chrome users), Flash Player 101.106.16 and earlier for Android. In addition, Adobe believes the bug lives in the “authplay.dll” component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Mac systems.”


9 Mar – New Java for Macs, a load of updates for Windows…

The turnaround for Java updates for Mac is very quick this time, and that’s good news. There was a lot of security problems in the last release from Oracle. Java Update 4 is available with the standard Update tool. You can read about the update here: About the security content of Java for Mac OS X 10.6 Update 4

Window Patch Tuesday also has critical updates, but that is usual and ‘do it now’ necessary.

Also ‘do it now’ necessary is a critical Shockwave update patch, and an Adobe Flash update available here.

As Krebs On Security points out, you must update for each browser that you have on your computer. Check whether you have the latest version at this page.

Krebs also points out that Apple has a new iTunes for Windows that has dozens of security fixes. Use the new Windows version of Apple Software Update that comes bundled with the iTunes. Why you have iTunes on your production computer that touches security keys is a different question. Rethink your security policies and always think Vigilance.

Patch Tuesday, Etc. — Krebs on Security


6 Mar – Check your Firefox Update. Two in the last few days. The latest is just a Java problem fix, but the last one and the one before that had more RED alerts to paint a stop sign.  Security Advisories for Firefox 3.6


24 Feb – Microsoft’s virus scanner causes security problem – The H Security: News and Features

Read the report.

This brings up: Why do we pay attention to Windows news when most all the servers out there are Linux based?

The answer comes from two directions. First, It is a rare facility in any part of the distribution chain that doesn’t have Windows machines as part of their production cycle. Emails are sent and received with Windows, keys are downloaded from windows, pdf files are downloaded from windows, which are put onto USB sticks. These USB sticks are put into systems that are dedicated to creating terrific movies – but they aren’t set up to be updated against the latest virus or trojan threat.

Viruses and Trojans can be designed to bounce around, doing nothing to intermediate systems, staying dormant until they reach the target machine. The code that they are made of doesn’t register as a virus by the transmitting machines, meaning that your desk computer won’t alert you if the pdf you put on your USB stick has a Linux virus.

In truth, it seems like a stretch to assume that someone would write a program for some target machine that requires several dozen steps before it is able to wreck havoc. But tell that to the Iranian Nuclear Facility. Tell that to the US Dept. of Defense, whose systems took two years to clear from a virus caught by a USB stick from a laptop of an employee.

DCinema systems are under the radar now. The movies on them are very secure. Only 11 of the 16 layers of AES-256 encryption have been broken. It is easier to pirate movies off the screen.

Which brings up the 2nd viewpoint: Proper security is done by design, not by luck.The habit of constant vigilance takes a long time to build.

Enough said.

6 Jan – Mac OS 10.6.6 released; among the 126Mb download is one security fix, having to do with an obscure man-in-the-middle attack. Most of the update seems to be interfacing the AppStore, except for a couple odd issues with the mouse pointer and cropping postscript. Doesn’t seem essential unless they are hiding something. But, it worked with no problems on my old MBP.

4 Jan – Imagine that…Microsoft starts the New Decade in a panic. Krebs on Security reports Microsoft Warns of Image Problem — a disappointing set of circumstances brought notice to this Graphics Engine bug because a Google spider broadcast it before Microsoft found a solution to this XP, 2003 Server and Vista security hole.

Microsoft’s solution – escalate access rights in such a way that thumbnail pictures are no longer displayed…ever. You can do that either with chaning shimgvw.dll library or buying a Mac.

IT Pro reports: “With Patch Tuesday due next week, Microsoft may fix numerous issues, including a flaw affecting all versions of Internet Explorer. Microsoft investigates Windows zero-day flaw | IT PRO

“Hackers could have take advantage of the security hole through a technique which lets attackers get around two important security defences in Windows 7 and Vista.

“Meanwhile, a Google researcher has warned details on a potentially serious vulnerability affecting the Microsoft browser could be in the hands of Chinese hackers.”

But, if someone you know is, read them this from H-Security: Microsoft issues warning about critical IE hole – An exploit recently went into circulation for a critical security flaw in Internet Explorer (IE), so you could infect your computer if you visit a specially crafted malicious website.

Krebs In Security makes the following points:

Note that this is not the sandboxed version (Adobe Reader X, or v 10.0) which is expected to be released at the end of this month.

Separately, the company is warning users not to fall for recent phishing and other e-mail scams targeted at Adobe customers looking for the Adobe Acrobat X, a new product being released this week. “Many of these emails require recipients to register and/or provide personal information. Please be aware that these emails have not been sent by Adobe or on Adobe’s behalf,” Adobe said.

19 October: Apple Mac Java Update: Amazing 1 week turnaround for an Apple Java Update. Use your standard Apple Update pulldown; many security vulnerability fixes. Very important.

Java for Mac OS X 10.6 Update 3
Java for Mac OS X 10.5 Update 8


20 October; RealPlayer is in the news with a new version that fixes seven critical vulnerabilities that they admit to, and remember, vulnerability means that they could be used to compromise host systems (that’s your computer) remotely if left unpatched.

Firefox fixes and Java passes Adobe in security exploits. (Clue – Exploits mean attacked and found attackable.)

According to Java surpasses Adobe kit as most attacked software • The Register,

Oracle’s Java framework has surpassed Adobe applications as the most attacked software package, according to a Microsoft researcher who warned she was seeing “an unprecedented wave of Java exploitation.”

Hmmm. A Microsoft spokesperson assailing Java and Oracle in one paragraph. This author apologizes for wasting your time. We’ll get less biased sources next time.

Meanwhile, Firefox’s 3.6.11 fixes several flaws that hackers have been using, so if your DCP passwords are coming off a system that is also using Firefox, upgrade now. Performance and stability are also improved. Mozilla Firefox 3.6.11 Release Notes

 


12 October – Who is comfortable seeing the Oracle name when you see the word Java? Notwithstanding, 30 bug and security fixes –  The official Java Download page. Not for Macs…they usually follow a while after, but the last MacJava update took care of a critical problem a month ago that is only now being fixed for everyone else.

 


5 October – After a long period (about 6 weeks) without a bug and security fix, Adobe releases new versions of Reader and Acrobat with the nuanced reason of “…a Flash player update as well as numerous bug fixes. Several security fixes are included as described here and here. The operative language is: “Critical vulnerabilities have been identified in Adobe Reader 9.3.4 (and earlier versions) for Windows, Macintosh and UNIX, Adobe Acrobat 9.3.4 (and earlier versions) … could cause the application to crash and could potentially allow an attacker to take control of the affected system. Adobe recommends users of Adobe Reader 9.3.4 and earlier versions for Windows, Macintosh and UNIX update to Adobe Reader 9.4. …”

 

Since I get 3 or 4 crashes a week with my Flash plug-in for Safari and don’t use Reader at all, this isn’t so critical to me. But I see dcinema players, and computers where people manipulate their keys, with different versions of Reader – none of them are what Adobe calls secure…well, they call them secure when released, but weeks later they change their minds.

The links above go to the Security Description pages on Apple’s website.

DO THIS UPDATE NOW. Depending on the cycle that you have set, you may not be notified of this update for a week or more. Crafty PDF coding is becoming rampant. Corporate solution: Encode your PDF files with version A, which can’t contain motion pictures and other un-needed things.

Adobe is also in the news with a new Flash for the Mac (This link goes to Adobe’s Tech PR). Your editor became a guinea pig this morning. The old MacBook Pro still works, if that means anything to you.  Download site is here. The version as of this morning was 10.1.82.76

DO THIS UPDATE NOW (ALSO) – It not only fixes security holes, but speed is improved:

“In internal testing, we’ve seen dramatic performance improvements — up to two-thirds reduction in CPU utilisation for 1080p H.264 video playback”, but it also has Security enhancements. Yes. I know.

29 July – Big App Upgrade Time

Firefox, Safari, Adobe Reader and Flash all have new upgrades that are required for security reasons. Put a couple hours of your weekend aside for back-ups and upgrades!

If you didn’t do Open Office to 3.2.1, better get that too.


25 June – Look for an important set of releases for all platforms which use Adobe Reader. Adobe brings forward security update for Reader


Whether you need or don’t need the functionality, Upgrade to the latest Apple everything; Safari 5, 10.6.4, Quicktime, Java…there are too many major repaired security holes to count and comment upon.


7 June – OpenOffice brings 2 security reports on the new version 3.2 (fixed with 3.2.1), including SSL/TLS and Python problems. Don’t delay.


5 June 2010 – Yet again, Adobe Flash, Reader and Acrobat is in the vulnerability news. H Security reports:

According to a security advisory from Adobe, there is a critical vulnerability in Flash Player 10.0.45.2 (and earlier versions) and in the authplay.dll component that ships with Adobe Reader and Acrobat 9.0; Windows, Mac OS X, Unix and Linux versions are all vulnerable. Attackers can exploit the hole to crash the software or gain control of the system and there are already reports of exploitation in the wild for all three products.

The Flash Player 10.1 release candidate is apparently not vulnerable and Adobe offer the option of installing this as a mitigation step. For Reader and Acrobat 9.x, Adobe recommend deleting, renaming or removing access to theauthplay.dll file to mitigate the threat. On Windows, this file is typically located at C:\Program Files\Adobe\Reader 9.0\Reader\authplay.dll for Adobe Reader or C:\Program Files\Adobe\Acrobat 9.0\Acrobat\authplay.dll for Acrobat. Adobe say that Reader and Acrobat 8.x are not vulnerable.


2 Jun 2010 – Finally, a Mac serious malware problem in the field. It ain’t a virus or a worm (though it can self-update), but it does send data and open a back door. Martin James, at IT Pro Security reports:

Security firm Intego has warned Mac OS X users that downloading free software from several popular download sites may install spyware that opens a back door for hackers to collect personal details.

The spyware, called OSX/OpinionSpy, is a variant of a Windows threat first discovered in 2008. It has been found piggy-backing on nearly 30 screensaver downloads from a company called 7art and a video converter app called MishInc FLV to MP3.

Softpedia, MacUpdate and VersionTracker were all found to be hosting the infected downloads, which have now been withdrawn, Intego said.

27 May—IT Pro Reports potential intercept vulnerability in Cisco’s Network Building Mediator products.

Cisco warns that there are numerous vulnerabilities that could lead to malicious parties taking complete control over affected devices. The NBM units are used in professional installations to monitor a building’s operations with IT; the status of doors, energy consuming devices, and overall efficiency.

Importantly, it is tied to the IT network where certain security gaps allow unauthorised users to change a device’s configuration.

“A malicious user must authenticate as an existing user but does not need to have administrator privileges or know administrator credentials to modify device configuration,” the company noted.

Other vulnerabilities mean that interactions between an operator workstation and the Cisco Network Building Mediator could be intercepted by any willing person.

“A malicious user able to intercept the sessions could learn any credentials used during intercepted sessions (for administrators and non-administrators alike) and could subsequently take full control of the device,” Cisco explained.

Other threats include potential password theft and account data loss.

As usual, whether you have the particular devices listed below, it is critical that your DCinema system stays secure, so awareness of all devices in the room is critical.

The weaknesses affect the legacy Richards-Zeta Mediator 2500 product and Cisco Network Building Mediator NBM-2400 and NBM-4800 models as well as Mediator Framework software releases prior to 3.1.1.

Given that the “workarounds” offered by Cisco are somewhat limited, affected firms will want to get hold of the free software updates that the provider has issued to deal with the security holes.


24 May—

IT Pro Security reports that IBM has distributed USB sticks at a conference in Australia this week which were riddled with malware – two separate worms to be exact – and the company was forced to send out emails to the recipients warning them and asking them to return the sticks to IBM’s Australian headquarters as soon as possible.

So, raise your hands if you ever used a give-away USB stick on your computer.

Again, the message; Constant Alertness. One clever trojan that can send log files outbound, or a pdf with a worm that can spread though a network and attach itself to media files, and the game gets too interesting.


14 April—Microsoft, Adobe and Oracle have all issued important security updates as part of this month’s Patch Tuesday. ITPro for Business

Microsoft has issued 11 patches to fix 25 flaws across Windows, Office and Exchange as part of its monthly update cycle.

Of the 11 patches, five were rated critical, five were important, and the last was moderate.

Microsoft highlighted three – MS10-019, MS10-026, and MS10-027 – as being priorities for administrators. The first affects all versions of Windows and allows for code to be executed, while the latter pair could be triggered just by visiting a malicious web page.

Microsoft’s security communications manager Jerry Bryant also warned that one of the patches is a Windows Kernel update, and therefore includes a system to check for rootkits, after the last kernel update uncovered a few infections.


8 April 2010—PDF virus spreads without exploiting any flaw

A security researcher has demonstrated a proof-of-concept attack that could allow malicious PDF files to spread to other PDF files on a system without exploiting a specific vulnerability.

 

Jeremy Conway, a product manager at NitroSecurity, built on the work done by fellow security specialist Didier Stevens to come up with an attack that could spread malicious code into clean PDFs as part of an incremental update.

Last week, Stevens showed how a program launch action triggered by the opening of a PDF could be exploited to execute code embedded in the PDF. Stevens also demonstrated that the pop-up dialogue box normally accompanying such a launch action could be partially manipulated to give users a false sense of security.

However, Conway – who says he was inspired by Stevens’ work – said the vulnerability could be used to infect other PDF files with the same problem.


17 Fevrier–Acrobat and Reader users are strongly encouraged to install an update that fixes ‘critical security holes’. ScanSafe reports that 80% of web-based exploits attacked Adobe Reader vulnerabilities.

 

Updates links for WindowsMac and Linux 9.3.1 version of Reader.

Firefox has also released their 3.6 version – much enhance security and speed.

Krebs on Security also reports:

If you decide to do without Adobe Reader and uninstall it, you might want to nix the Adobe Download Manager as well. Researcher Aviv Raff points to some nifty work he’s done which shows that Adobe’s Download Manager — which ships with all new versions of Flash and Reader — can be forced to reinstall an application that’s been removed, such as Reader.

According to Raff, a Web site could hijack the Adobe Download manager to download and install any of the following:

Adobe Flash 10

  • Adobe Reader 9.3
  • Adobe Reader 8.2
  • Adobe Air 1.5.3
  • ARH tool – allows silent installation of Adobe Air applications
  • Google Toolbar 6.3
  • McAfee Security Scan Plus
  • New York Times Reader (via Adobe Air)
  • Fanbase (via Adobe Air)
  • Acrobat.com desktop shortcut

Raff writes: “So, even if you use an alternative PDF reader, an attacker can force you to download and install Adobe Reader, and then exploit the (yet to be patched, but now known) vulnerability. The attacker can also exploit 0-day vulnerabilities in any of the other products mentioned above.” Read more on his findings atthis link here.

Along with 13 update bundles and a critical rating for this months exploit vulnerability patches, Microsoft is stealing the Nike slogan, saying “Just freakin’ do it” – change your operating system, change anything that came with it (Paint, anyone?), especially that Internet Explorer dated from 6 years ago…and XP too while you are at it.

20 Jan, 2010–In a wave of ‘finally’, Apple and Shockwave get much needed security upgrades. For Apple, use the update utility, or go to Apple-Support-Downloads; they have also finally caught up with the Windows 7 upgrade for Bootcamp.

Shockwave is a bit heavier, and applies to both PCs and Macs. It requires a manual uninstall, a reboot, an install, and another reboot. But, it is supposed to fill the glaring hole that has been present (and exploited) security risk: The patches fix multiple integer overflow and buffer overflow flaws that can be exploited to execute malicious code on computers that use the software.

Get your Shockwave 11.5.2.602 here.

 


This is the Friday, 15 Jan Report

Finally—Adobe Reader is safe. Well, at least it no longer has the hole that was allowing people in for the last few months. Update Now. Read no more. This is all for now. Even Firefox is playing nice.


December Firefox 3.5.6 handles 3 critial security issues – great strides from the two previous releases. There were 62 bug fixes. Seems like a lot of work for handling a version that will be superceded in the next few months, but 3.6 is still in alpha. (We have been informed that 3.0 is losing support as of Jan 2010.)

Meanwhile, Adobe can only be described as refusing to fix the zero-day trojan that has active exploits, until January 12. This strikes Windows systems at the current software rev, 9.2 and below…since anything below passed other problems like a sieve, this is not a good solution.

Hire someone to check your virus protection on a regular basis if you are using Windows.

See articles at CNET Security; Firefox 3.5.6 patches and Adobe to patch zero-day Reader, Acrobat hole [BFD-Editor] – Note the part where Adobe says that they’d rather not spend the extra time and money over the holidays to fix this hole.


This weekend is a great one for setting aside whatever time it takes to back up everything and then replace each program that you use with the latest version.

Looking at the security notes for this weeks releases of Safari, and Firefox, Adobe Shockwave and the recent Reader upgrades are downright scary. The Operating Systems changes were also important.

Cute little terms like ‘unexpected application termination or arbitrary code execution” and “maliciously crafted website may lead to the disclosure of local information.” A less subtle writer might put exclamation points after a big “WTF?’

Don’t waste time reading any more of this note than you must.

1) Buy whatever backup disk you need

2) Back up Now!

3) Open every program that you use. Check for an update.

4) Then, when your updates are finished…Back up again.

That is all. Go. Now. Please. I don’t want to read your complaints about arbitrary code disclosing your local information.
