Reports have surfaced about a new security hole that has been in Windows since the release of Windows NT 3.1 on July 27, 1993. The vulnerability is present in all 32-bit versions of Windows released since then, including Windows 7.

Thankfully, the flaw isn’t in a commonly used application but in the Virtual DOS Machine (VDM) used to support 16-bit applications. There are several vulnerabilities in this implementation, according to Google security team member Tavis Ormandy, who found the issues.
