Description: A vulnerability has been discovered in Microsoft Windows, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the Microsoft Vector Graphics Rendering(VML) library (vgx.dll) when processing certain content in Vector Markup Language (VML) documents. This can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into viewing a malicious VML document containing an overly long "fill" method inside a "rect" tag with the Internet Explorer browser.
Successful exploitation allows execution of arbitrary code with the privileges of the application using the vulnerable functionality in the library.
NOTE: The vulnerability is currently being actively exploited.
The vulnerability is confirmed on a fully patched Microsoft Windows XP SP2 system. Other versions may also be affected.
According to Microsoft, other unspecified vulnerabilities also exist.
