Adobe Product Security Incident Response Team (PSIRT) has been posted about a critical vulnerability in Adobe Reader 9.1 and Acrobat 9.1 and earlier versions. This vulnerability (CVE-2009-1492) would cause the application to crash and could potentially allow an attacker to take control of the affected system. A second vulnerability has also been reported that appears to affect Adobe Reader for Unix only (CVE-2009-1493).

Adobe is planning to release product updates to Adobe Reader and Acrobat to resolve the relevant security issues. Adobe expects to make available Windows updates for Adobe Reader versions 9.X, 8.X, and 7.X and Acrobat versions 9.X, 8.X, and 7.X, Macintosh updates for Adobe Reader versions 9.X and 8.X and Acrobat versions 9.X and 8.X, as well as Adobe Reader for Unix versions 9.X and 8.X, by May 12th, 2009. The Adobe Reader for Unix updates will resolve both security issues. A security bulletin will be published at http://www.adobe.com/support/security as soon as product updates are available.
