Adobe has released updates to mitigate critical vulnerabilities in the company's Adobe Reader and Acrobat products.
The vulnerabilities addressed leave systems open to remote access and control, system crashes, and denial of service exploits.
"These updates address critical vulnerabilities in Adobe Reader X (10.1.1) and earlier versions for Windows and Macintosh, and Adobe Acrobat X (10.1.1) and earlier versions for Windows and Macintosh. These vulnerabilities could cause the application to crash and potentially allow an attacker to take control of the affected system. These updates include fixes for CVE-2011-2462 and CVE-2011-4369, previously addressed in Adobe Reader and Acrobat 9.x for Windows as referenced in Security Bulletin APSB11-30," the Adobe advisory states.

"Adobe recommends users of Adobe Reader X (10.1.1) and earlier versions for Windows and Macintosh update to Adobe Reader X (10.1.2). For users of Adobe Reader 9.4.7 and earlier versions for Windows and Macintosh, who cannot update to Adobe Reader X (10.1.2), Adobe has made available the update Adobe Reader 9.5. Adobe recommends users of Adobe Acrobat X (10.1.1) for Windows and Macintosh update to Adobe Acrobat X (10.1.2).
