Critical vulnerability in Adobe Flash Player

A critical vulnerability exists in Adobe Flash Player 10.2.152.33 and earlier versions for Windows, Macintosh, Linux and Solaris operating systems (Adobe Flash Player 10.2.154.18 and earlier for Chrome users), 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 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.

Adobe is not currently aware of attacks targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.

Adobe 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.

Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing. 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.

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