Security Advisory for Adobe Flash Player, Adobe Reader and Acrobat

Release date: March 14, 2011

Last updated: March 14, 2011

Vulnerability identifier: APSA11-01

CVE number: CVE-2011-0609

Platform: All Platforms

SUMMARY

A critical vulnerability exists in Adobe Flash Player 10.2.152.33 and
earlier versions (Adobe Flash Player 10.2.154.18 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.

and Acrobat 8.x are not affected by this issue.
