Critical Adobe and Adobe Acrobat Update

Adobe has taken to using the same "patch Tuesday" as Microsoft. If you use Adobe Reader or Adobe Acrobat, it is strongly advised that you update as soon as possible. Personally, for home use, I have replaced Adobe Reader with an alternate PDF reader. There are a number of open source readers available from http://pdfreaders.org/.
From the Adobe Security Bulletin:

Summary

Critical vulnerabilities have been identified in Adobe Reader 9.3.1 (and earlier versions) for Windows, Macintosh, and UNIX, Adobe Acrobat 9.3.1 (and earlier versions) for Windows and Macintosh, and Adobe Reader 8.2.1 (and earlier versions) and Adobe Acrobat 8.2.1 (and earlier versions) for Windows and Macintosh. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.

Adobe recommends users of Adobe Reader 9.3.1 and earlier versions for Windows, Macintosh and UNIX update to Adobe Reader 9.3.2. (For Adobe Reader users on Windows and Macintosh, who cannot update to Adobe Reader 9.3.2, Adobe has provided the Adobe Reader 8.2.2 update.) Adobe recommends users of Adobe Acrobat 9.3.1 and earlier versions for Windows and Macintosh update to Adobe Acrobat 9.3.2. Adobe recommends users of Acrobat 8.2.1 and earlier versions for Windows and Macintosh update to Acrobat 8.2.2.
