Update on Adobe Reader, Acrobat and Flash Player Issue

A Security Advisory has been posted in regards to the Adobe Reader, Acrobat and Flash Player issue discussed in the Adobe PSIRT blog on July 21 (“Potential Adobe Reader, Acrobat, and Flash Player issue“, CVE-2009-1862). A critical vulnerability exists in the current versions of Flash Player (v9.0.159.0 and v10.0.22.87) for Windows, Macintosh and Linux operating systems, and the authplay.dll component that ships with Adobe Reader and Acrobat v9.x for Windows, Macintosh and UNIX operating systems. This vulnerability (CVE-2009-1862) 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 via limited, targeted attacks against Adobe Reader v9 on Windows.
We are in the process of developing a fix for the issue, and expect to provide an update for Flash Player v9 and v10 for Windows, Macintosh, and Linux by July 30, 2009 (the date for Flash Player v9 and v10 for Solaris is still pending). We expect to provide an update for Adobe Reader and Acrobat v9.1.2 for Windows, Macintosh, and UNIX by July 31, 2009.
Deleting, renaming, or removing access to the authplay.dll file that ships with Adobe Reader and Acrobat v9.x mitigates the threat for those products, but users will experience a non-exploitable crash or error message when opening a PDF that contains SWF content. Depending on the product, the authplay.dll that ships with Adobe Reader and Acrobat 9.x for Windows is typically located at C:\Program Files\Adobe\Reader 9.0\Reader\authplay.dll or C:\Program Files\Adobe\Acrobat 9.0]\Acrobat\authplay.dll. Windows Vista users should consider enabling UAC (User Access Control) to mitigate the impact of a potential exploit. Flash Player users should exercise caution in browsing untrusted websites. Adobe is in contact with Antivirus and Security vendors regarding the issue and recommend users keep their anti-virus definitions up to date.
We will continue to provide updates on this issue via the Security Advisory section of the Adobe web site, as well as the Adobe PSIRT blog.
