Security bulletin

Security updates available for Adobe Reader and Acrobat

   Release date: April 21,2011

   Vulnerability identifier: APSB11-08

   CVE number: CVE-2011-0611, CVE-2011-0610

   Platform: All Platforms

Summary

   Critical vulnerabilities have been identified in Adobe Reader and
   Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and
   Macintosh operating systems.  These vulnerabilities, including
   CVE-2011-0611, as referenced in Security Advisory APSA11-02, could
   cause a crash and potentially allow an attacker to take control of the
   affected system.  There are reports that one of the vulnerabilities,
   CVE-2011-0611, is being actively exploited in the wild against both
   Adobe Flash Player, and Adobe Reader and Acrobat, as well as via a
   Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft
   Excel (.xls) file delivered as an email attachment targeting the
   Windows platform. Adobe Reader X Protected Mode mitigations would
   prevent an exploit of this kind from executing.

   Adobe recommends users of Adobe Reader X (10.0.2) for Macintosh update
   to Adobe Reader X (10.0.3). For users of Adobe Reader 9.4.3 for
   Windows and Macintosh, Adobe has made available the update, Adobe
   Reader 9.4.4.  Adobe recommends users of Adobe Acrobat X (10.0.2) for
   Windows and Macintosh update to Adobe Acrobat X (10.0.3). Adobe
   recommends users of Adobe Acrobat 9.4.3 for Windows and Macintosh
   update to Adobe Acrobat 9.4.4. Because Adobe Reader X Protected Mode
   would prevent exploits of the type targeting CVE-2011-0611 from
   executing, we are currently planning to address these issues in Adobe
   Reader X for Windows with the next quarterly security update for Adobe
   Reader, currently scheduled for June 14, 2011. Today's security
   updates are out-of-cycle updates.

Affected software versions

     * Adobe Reader X (10.0.1) and earlier versions for Windows
     * Adobe Reader X (10.0.2) and earlier versions for Macintosh

   Reader and Acrobat 8.x are not affected by CVE-2011-0611.
