This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of sockets. The issue lies in the failure to properly handle error conditions leading to a pointer not being reset. An attacker can leverage this vulnerability to raise privileges and execute code under the context of SYSTEM.
