A crititcal security patch for Adobe Reader, Acrobat and Flash player has been released.

The vulnerability is found in 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.

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. Adobe is in contact with Antivirus and Security vendors regarding the issue and recommend users keep their anti-virus definitions up to date.
