There have been reports of two critical vulnerabilities being actively exploited in limited, targeted attacks in the wild against Adobe Reader 9.x on Windows. These vulnerabilities (CVE-2011-2462, referenced in Security Advisory APSA11-04, and CVE-2011-4369) could cause a crash and potentially allow an attacker to take control of the affected system.

While these vulnerabilities exist in Adobe Reader X (10.1.1) and earlier versions for Windows and Macintosh, Adobe Reader 9.4.6 and earlier 9.x versions for UNIX, and Adobe Acrobat X (10.1.1) and earlier versions for Windows and Macintosh, there is no immediate risk to users of Adobe Reader and Acrobat X for Windows (with Protected Mode/Protected View enabled), Adobe Reader and Acrobat X or earlier versions for Macintosh, and Adobe Reader 9.x for UNIX based on the current exploits and historical attack patterns.

Today's updates address these vulnerabilities in Adobe Reader and Acrobat 9.x for Windows. Adobe recommends users of Adobe Reader 9.4.6 and earlier 9.x versions for Windows update to Adobe Reader 9.4.7. Adobe recommends users of Adobe Acrobat 9.4.6 and earlier 9.x versions for Windows update to Adobe Acrobat 9.4.7.

Because Adobe Reader X Protected Mode and Adobe Acrobat X Protected View would prevent an exploit of the type currently targeting these vulnerabilities (CVE-2011-2462 and CVE-2011-4369) from executing, we are planning to address these issues in Adobe Reader and Acrobat X for Windows with the next quarterly security update for Adobe Reader and Acrobat, scheduled for January 10, 2012. We are planning to address these issues in Adobe Reader and Acrobat X and earlier versions for Macintosh as part of the next quarterly update scheduled for January 10, 2012. An update to address these issues in Adobe Reader 9.x for UNIX is planned for January 10, 2012. For further context on this schedule, please see the corresponding ASSET blog post.
