The version of Adobe Reader installed on the remote host is earlier than 10.1.2 / 9.5, and therefore affected by multiple memory corruption vulnerabilities. An attacker could exploit these issues by tricking a user into opening a maliciously crafted Reader file, resulting in arbitrary code execution.
Adobe Reader 10.1.2 is the first 10.x release to include fixes for CVE-2011-2462 and CVE-2011-4369. These were previously fixed for 9.x releases in 9.4.7 (APSB11-30).
