Security Advisory for Adobe Flash Player, Adobe Reader and Acrobat
Release date: October 28, 2010

Vulnerability identifier: APSA10-05

CVE number: CVE-2010-3654

Platform: All Platforms

Summary: A critical vulnerability exists in Adobe Flash Player 10.1.85.3 and earlier versions for Windows, Macintosh, Linux and Solaris operating systems; Adobe Flash Player 10.1.95.2 and earlier versions for Android; and the authplay.dll component that ships with Adobe Reader 9.4 and earlier 9.x versions for Windows, Macintosh and UNIX operating systems, and Adobe Acrobat 9.4 and earlier 9.x versions for Windows and Macintosh operating systems.

This vulnerability (CVE-2010-3654) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild against Adobe Reader and Acrobat 9.x. Adobe is not currently aware of attacks targeting Adobe Flash Player.

We are in the process of finalizing a fix for the issue and expect to provide an update for Flash Player 10.x for Windows, Macintosh, Linux, and Android by November 9, 2010. We expect to make available an update for Adobe Reader and Acrobat 9.4 and earlier 9.x versions during the week of November 15, 2010.
