Patch Tuesday: Windows, Microsoft Office, Adobe Shockwave all get critical patches

Well, yesterday was a quiet Patch Tuesday, but the Microsoft patches are listed as "Critical" on the SANS page. My own systems patched without problems and I'm not seeing any reports of issues elsewhere, so I will be applying them on client systems later this week. Home users should update themselves.

May 2010 Microsoft Patches
Overview of the May 2010 Microsoft Patches and their status.

Patch Tuesday: Microsoft plugs Windows worm holes | ZDNet
Microsoft today issued patches for a pair of critical (remote code execution) vulnerabilities in Windows and Microsoft Office and urged affected users to apply the fixes as soon as possible.

In addition, to Microsoft, Adobe issued a patch rated "Critical", but it only affects those few people who have the Adobe Shockwave Player (this is different from the "Shockwave Flash Player" which almost everyone has installed. NOTE: last time Adobe updated the Shockwave Player, you had to manually uninstall the older version first, then reboot, then install the new version. I haven't found out if that is necessary this time.

Adobe zaps critical Shockwave vulnerabilities | ZDNet
Adobe joined the Patch Tuesday train today with the release of patches for at least 21 documented security vulnerabilities in the Shockwave and ColdFusion product lines.

According to the APSB10-12 security bulletin, 18 of the 21 flaws affected the Shockwave Player, a free software product that lets users view rich-media content on the web.

Critical vulnerabilities have been identified in Adobe Shockwave Player 11.5.6.606 and earlier versions for Windows and Macintosh. The vulnerabilities could allow an attacker, who successfully exploits these vulnerabilities, to run malicious code on the affected system.

This bulletin is rated “critical” and Adobe recommends users of Adobe Shockwave Player 11.5.6.606 and earlier versions update to Adobe Shockwave Player 11.5.7.609.

Here's a link to the bulletin: Adobe - Security Bulletins: APSB10-12 - Security update available for Shockwave Player

You can also use Mozilla's free Plugin Check page to check on which plugins you have and which need updating, but you have to enable scripting on the page and it only has "Limited" support for IE7+. There's a blog entry on the Mozilla Security blog about it here: Plugin Check for Everyone at Mozilla Security Blog

Apple Safari 0-day flaw found

Multiple reports on this today.  The only Windows users who I've seen with Safari were those unfortunates who got tricked into installing it by the Apple iTunes or QuickTime updating software.  You're best off IMHO uninstalling Safari completely and using either Firefox or ChromePlus.  Additional info can be found at links in the following articles:

Critical zero-day flaw found in Apple's Safari browser - SC Magazine US
A “highly critical” zero-day vulnerability has been discovered in Apple's Safari web browser, according to Danish vulnerability tracking firm Secunia.

The code execution vulnerability, revealed Friday, affects the current version (4.0.5) of Safari for Windows and could allow an attacker to compromise a user's system. Other versions of the browser could also be affected.
Unpatched drive-by download flaw in Apple Safari browser | ZDNet
A zero-day vulnerability in Apple’s Safari browser could expose millions of Windows users to drive-by download malware attacks. The flaw is currently unpatched.

According to an alert from Secunia, the issue is rated “highly critical” because of the risk of remote code execution attacks that can lead to complete system takeover.
US-CERT Current Activity: Apple Safari Vulnerability
added May 10, 2010 at 10:57 am

US-CERT is aware of a vulnerability affecting Apple Safari. By convincing a user to open a specially crafted web page, an attacker may be able to execute arbitrary code. Exploit code for this vulnerability is publicly available.

US-CERT encourages users and administrators to disable JavaScript as detailed in the Securing Your Web Browser document until a fix is provided by the vendor. Additional information regarding this vulnerability can be found in the Vulnerability Notes Database.

US-CERT will provide additional information as it becomes available.

Emergency Java patch released, PATCH NOW

There have been reports that this flaw is already being exploited on at least one popular website.

As attacks surface, Sun ships sudden Java patch | Zero Day | ZDNet.com
In a sudden about-face, Sun has rushed out a Java update to fix a drive-by download vulnerability that exposed Windows users to in-the-wild malware attacks.

The patch comes less than a week after Sun told a Google researcher it did not consider the issue serious enough to warrant an out-of-cycle patch and less than a day after researchers spotted live exploits on a booby-trapped song lyrics Web site.

The release notes that accompanies the new Java 6 Update 20 makes no mention of the public flaw disclosure or subsequent attacks but I’ve been able to confirm that the patch does cover the vulnerability released by Google security researcher Tavis Ormandy.

Critical Java Vulnerability Exploited On Songlyrics.com | CyberInsecure.com
A popular song lyrics website has been found serving attack code that tries to exploit a critical vulnerability in Oracle’s Java virtual machine, which is installed on hundreds of millions of computers worldwide.

Java Patch Targets Latest Attacks — Krebs on Security
"Oracle Corp. has shipped a new version of its Java software that nixes a feature in Java that hackers have been using to foist malicious software.

Java 6 Update 20 was released sometime in the last 24 hours, and includes some security fixes, although Oracle’s documentation on that front is somewhat opaque. Most significantly, the update removes a feature that hackers have started using to install malware.

On Wednesday, a popular song lyrics Web site was compromised and seeded with code that leverages this Java feature to plant malicious software.

If you need Java for some specific reason, then by all means install this update. However, I have found that most users can happily do without this powerful and feature-rich program, which is fast becoming a popular vehicle for launching a range of attacks. More on that in a future post. Stay tuned.

System administrators and savvy home users who download the offline patch can update their computers more quickly by running the downloaded patch with the command-line switches "/passive /norestart". This turns the install into a start-it-and-forget-it event and avoids the need to click a bunch of [OK] and [Next] buttons. Incidentally, it also bypasses the attempt to install a toolbar into your browser. If you are curious about what command-line switches are available, run the patch with the command-line switch "/?".

Dangerous Java flaw being exploited in the wild

Just one more reason to use DropMyRights (there is a good 3-part write-up on it here) to run any Internet-facing application like browsers, email, music players, and so forth, and why you should use Firefox with NoScript and AdBlock Plus as your primary browser. Of course, you could also run as a Limited User, which is what I do on my home computer, but business users often have software which requires administrator rights on XP. Anyway, I recommend Firefox+NoScript or disabling Java until this is fixed.

Java zero-day flaw under active attack | Zero Day | ZDNet.com
Just days after Google researcher Tavis Ormandy released details on a dangerous new Java vulnerability, malicious hackers have pounced and are exploiting the flaw in the wild to launch drive-by download attacks.

Virus hunters have spotted the attacks on a popular song lyrics Web site. Any visitor to that Web site with the Java Plugin for Browsers installed (Internet Explorer or Firefox) will get infected with malware.

According to AVG’s Roger Thompson, the attacks are likely to spread because of the simplicity in launching a successful exploit: ....


Unpatched Java Exploit Spotted In-the-Wild — Krebs on Security
Last week, a Google security researcher detailed a little-known feature built into Java that can be used to launch third-party applications. Today, security experts unearthed evidence that a popular song lyrics Web site was compromised and seeded with code that leverages this Java feature to install malicious software.

On April 9, Google researcher Tavis Ormandy posted to the FullDisclosure mailing list that he’d discovered he could abuse a feature in Java to launch arbitrary applications on a Windows PC using a specially-crafted Web site. Ormandy said the feature had been included in every version of Java since Java 6 Update 10, and was intended as a way to make it easier for developers to distribute their applications. Along with that disclosure, Ormandy published several examples of how attackers might use this functionality in Java to load malicious applications onto a user’s system.

As of this morning, songlyrics.com, a site that according to traffic analysis firm compete.com receives about 1.7 million visits each month, was loading code from assetmancomcareers.com, a Russian Web site with a history of pushing rogue anti-virus.

Quicktime, Foxit Reader patched last week

I meant to blog this last week, but it fell off the stack until this week's security blog came around on the keyboard. On top of last week's Mega Patch collection, here are two more:

Security Updates for Foxit, QuickTime/iTunes — Krebs on Security
Foxit Software has issued an update to make it easier for users to spot PDF files that may contain malicious content. Also, Apple has pushed out new versions of QuickTime and iTunes that correct nearly two dozen security problems in those programs.
