In what seems to be yet one more vulnerability found in a string of recent ones, Adobe said a few days ago it would issue an emergency patch the week of Aug. 16 to fix a critical flaw in its Reader and Acrobat software.
The bug was disclosed at last month’s Black Hat USA 2010 security conference (Black Hat: a series of highly technical security briefings held annually). Shortly after Adobe announced it would release a rush security update during the week of Aug. 16-20. Adobe issues its quarterly security updates for Reader and Acrobat on Tuesdays, and has shipped emergency fixes on that same day of the week. If the company continues the practice, it would most likely deliver the out-of-band patch later today, Aug. 17.

Adobe hinted that the out-of-band update will include fixes for vulnerabilities other than the one recently uncovered. The company also said it would still ship its next regularly-scheduled quarterly update on Oct. 12.

Affected software versions

Adobe Reader 9.3.3 and earlier versions for Windows, Macintosh, and UNIX
Adobe Acrobat 9.3.3 and earlier versions for Windows and Macintosh

Vulnerability has been classified as critical. As usual, make sure you update your Adobe Acrobat and Reader version as soon as possible, if not earlier 🙂
