Release Date:
4/13/2004 12:00:00 AM

Date Reported:

Severity:
High

Vendor:
Microsoft

Affected Software:
Windows NT 4.0
Windows 2000
Windows XP

Overview:

Technical Details:
eEye Digital Security has discovered a buffer overflow in the APIs which handle Windows metafile-format images, implemented in the Windows GDI Client DLL (GDI32.dll). A Windows metafile is a collection of structures that stores a picture in a device-independent format. The GDI32.dll PlayMetaFileRecord() API, which plays a Windows-format metafile record by executing GDI functions specified within the record, has been found to contain an exploitable heap overflow.

A Windows metafile can be handled by many applications such as Internet Explorer, Outlook Express, Wordpad, the Windows shell (Explorer), the Office series (Word/Excel/PowerPoint/Outlook, etc.), and other third party applications. If any of these applications handle the corrupted metafile, it is possible to execute arbitrary code contained within the Windows metafile.

Protection:
Retina Network Security Scanner has been updated to identify this vulnerability.

Vendor Status:
Microsoft has released a patch for this vulnerability. The patch is available at: http://www.microsoft.com/technet/security/bulletin/MS04-011.mspx.
