Microsoft Windows may be vulnerable to remote code execution via a buffer overflow in the Windows Metafile image format handling.
Windows Metafile (WMF) format images are metafiles that can contain both vector and bitmap-based information. Microsoft Windows contains routines for displaying WMF files. However, a lack of input validation in on of these routines may allow a buffer overflow to occur, and in turn may allow remote arbitrary code execution.
A remote, unauthenticated attacker may be able to execute arbitrary code if the user is persuaded to view a specially-crafted WMF file.
