A critical vulnerability exists in Adobe Reader 9.3.4 and earlier versions for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh. This vulnerability (CVE-2010-2883) 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.
We are in the process of finalizing a fix for the issue and expect to provide updates for Adobe Reader 9.3.4 for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 for Windows and Macintosh during the week of October 4, 2010.
Please note that these Adobe Reader and Acrobat updates represent an accelerated release of the next quarterly security update originally scheduled for October 12, 2010. With this accelerated schedule, we do not plan to release any new updates for Adobe Reader and Acrobat on October 12, 2010.
Current exploits in the wild target the Windows platform. Customers using Adobe Reader or Acrobat 9.3.4 or earlier on Windows can utilize Microsoft's Enhanced Mitigation Evaluation Toolkit (EMET) to help prevent this vulnerability from being exploited. For more information on EMET and implementing this mitigation, please refer to the Microsoft Security Research and Defense blog. Note that due to the time-sensitive nature of this issue, testing of the functional compatibility of this mitigation has been limited. Therefore, we recommend that you also test the mitigation in your environment to minimize any impact on your workflows.
