Adobe is issuing an earlier-than-scheduled update for Reader and Acrobat on June 29 that will replace its originally scheduled July 13 quarterly update.

Patches will affect Adobe Reader 9.3.2 for Windows, Mac and UNIX, Adobe Acrobat 9.3.2 for Windows and Mac, and Adobe Reader 8.2.2 and Acrobat 8.2.2 for Windows and Mac.

The accelerated updates are in response to multi-platform security vulnerabilities Adobe advised on June 10 and resolve critical security issues that cause crashes and allow hackers to take over control of machines remotely.

Adobe had moved to patch similar security vulnerabilities earlier this month for the company’s Flash Player, which was done in five days.
