Platform: Windows

Summary

Critical vulnerabilities have been identified in Adobe Reader and Acrobat 7.0 through 7.0.8 that could — although Adobe is not aware of any specific code exploits at this time — allow an attacker who successfully exploits these vulnerabilities to take control of the affected system.

Solution

Adobe Reader on Windows: Adobe strongly recommends upgrading to Adobe Reader 8, available from the following site: http://www.adobe.com/go/getreader/.

Users with Adobe Reader 7.0 through 7.0.8, who cannot upgrade to Reader 8, should upgrade to Reader 7.0.9. Adobe Reader 7.0.9 is available as a full installation package and not a patch. It can be installed on top of any older version of Reader 7 and user preferences will be preserved: http://www.adobe.com/go/getreader/.

Solution: Adobe Acrobat on Windows: For version 7.0–7.0.8, users should utilize the product's automatic update facility. The default installation configuration runs automatic updates on a regular schedule, and can be manually activated by choosing Help > Check For Updates Now. Alternatively, the update files can also be manually downloaded and installed from http://www.adobe.com/downloads/.
