Security updates available for Adobe Reader and Acrobat

Release date: March 21, 2011

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.)
