Security Advisory for Adobe Flash Player, Adobe Reader and Acrobat

Release date: March 14, 2011
Vulnerability identifier: APSA11-01
CVE number: CVE-2011-0609
Platform: All Platforms
Severity Rating: Critical

Summary

A critical vulnerability exists in Adobe Flash Player 10.2.152.33 and earlier versions (Adobe Flash Player 10.2.154.13 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris operating systems, Adobe Flash Player 10.1.106.16 and earlier versions for Android, and the Authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions of Reader and Acrobat for Windows and Macintosh operating systems.

This vulnerability (CVE-2011-0609) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Excel (.xls) file delivered as an email attachment. At this time, Adobe is not aware of attacks targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.

We are in the process of finalizing a fix for the issue and expect to make available an update for Flash Player 10.x and earlier versions for Windows, Macintosh, Linux, Solaris and Android, and an update for Adobe Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Macintosh, Adobe Reader X (10.0.1) for Macintosh, and Adobe Reader 9.4.2 and earlier 9.x versions during the week of March 21, 2011. Because Adobe Reader X Protected Mode would prevent an exploit of this kind from executing, we are currently planning to address this issue in Adobe Reader X for Windows with the next quarterly security update for Adobe Reader, currently scheduled for June 14, 2011.

Affected software versions

• Adobe Flash Player 10.2.152.33 and earlier versions for Windows, Macintosh, Linux and Solaris operating systems
• Adobe Flash Player 10.2.154.13 and earlier for Chrome users
• Adobe Flash Player 10.1.106.16 and earlier for Android
• 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 Macintosh operating systems.

NOTE: Adobe Reader 9.x for UNIX, Adobe Reader for Android, and Adobe Reader and Acrobat 8.x are not affected by this issue.

Background on APSA11-01 Patch Schedule
Mar 14, 2011 9:17AM PDT

From the Adobe Secure Software Engineering Team (ASSET) Blog:

We just posted Security Advisory APSA11-01 announcing a critical vulnerability (CVE-2011-0609) in Adobe Flash Player, which also impacts the authplay.dll component shipping with Adobe Reader and Acrobat for Windows and Macintosh.

In the advisory, we referenced the following target ship schedule for the security updates addressing CVE-2011-0609 in Adobe Flash Player, Adobe Reader and Acrobat:

• The security update for Adobe Flash Player 10.x and earlier versions for Windows, Macintosh, Linux, Solaris and Android is scheduled to be available during the week of March 21, 2011.

• The security update for Adobe Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Macintosh, and Adobe Reader 9.4.2 and earlier 9.x versions is also scheduled to be available by the week of March 21, 2011.

• We currently plan to address CVE-2011-0609 in Adobe Reader X with the next quarterly security update for Adobe Reader, currently scheduled for June 14, 2011.

Let me provide some additional background on the decision not to update Adobe Reader X at this time. We evaluated a number of different options. In the end, we determined that the above patch schedule would allow us to provide the best balance of risk mitigation and admin/update costs for our customers. Here are some points we considered in developing this schedule:

• Reports that we've received thus far indicate the attack is targeted at a very small number of organizations and limited in scope. The current attack leverages a malicious Flash (.swf) file inside a Microsoft Excel (.xls) file. The .xls file is used to set up machine memory to take advantage of a crash triggered by the corrupted .swf file. The final step of the attack is to install persistent malware on the victim's machine.

• We have not received reports or malicious samples of attacks leveraging this vulnerability via .pdf files. However, attackers have leveraged these type of Flash Player vulnerabilities in the past via .pdf files to attack the embedded authplay.dll component shipping with Adobe Reader and Acrobat v9. Out of a preponderance of caution we took the decision to ship out-of-cycle updates for Adobe Reader and Acrobat v9, and Acrobat X to mitigate the risk of attackers shifting the attack from an .xls container to a .pdf container.

Vulnerability identifier: APSB11-06
CVE number: CVE-2011-0609
Platform: Windows and Macintosh

Summary:

A critical vulnerability has been identified 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 Macintosh operating systems. This vulnerability (CVE-2011-0609), as referenced in Security Advisory APSA11-01, could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Excel (.xls) file delivered as an email attachment. At this time, Adobe is not aware of attacks targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.

Adobe recommends users of Adobe Reader X (10.0.1) for Macintosh update to Adobe Reader X (10.0.2). For users of Adobe Reader 9.4.2 for Windows and Macintosh, Adobe has made available the update, Adobe Reader 9.4.3. Adobe recommends users of Adobe Acrobat X (10.0.1) for Windows and Macintosh update to Adobe Acrobat X (10.0.2). Adobe recommends users of Adobe Acrobat 9.4.2 for Windows and Macintosh update to Adobe Acrobat 9.4.3. Because Adobe Reader X Protected Mode would prevent an exploit of this kind from executing, we are planning to address this issue in Adobe Reader X for Windows with the next quarterly security update for Adobe Reader, currently scheduled for June 14, 2011.

(Note: Adobe Reader 9.x for UNIX, Adobe Reader for Android, and Adobe Reader and Acrobat 8.x are not affected by this issue.)
