Summary

A critical vulnerability exists in Adobe Flash Player 10.0.45.2 and earlier versions for Windows, Macintosh, Linux and Solaris operating systems, and the authplay.dll component that ships with Adobe Reader and Acrobat 9.x for Windows, Macintosh and UNIX operating systems. This vulnerability (CVE-2010-1297) 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 against both Adobe Flash Player, and Adobe Reader and Acrobat.

Please note that the Acrobat and Reader update represents an accelerated release of the next quarterly security update originally scheduled for July 13, 2010. With this accelerated scheduled we do not plan to release any new updates for Adobe Reader and Acrobat on July 13, 2010.
