The version of Adobe Reader on the remote Windows host is affected by multiple memory corruption vulnerabilities.
The remote Windows host contains a version of Adobe Reader 9.x < 9.4.4 or 10.x <= 10.1. Such versions are affected by multiple memory corruption vulnerabilities. A remote attacker could exploit this by tricking a user into viewing a maliciously crafted PDF file, resulting in arbitrary code execution. Note that Adobe Reader X Protected Mode prevents an exploit of this kind from executing. Note also, CVE-2011-0611 is being exploited in the wild as of April 2011.
