Description:
Symantec has reported a vulnerability in certain old versions of Windows, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an integer overflow error in the graphics rendering engine when processing WMF (Windows Metafile) images. This can be exploited to cause a heap-based buffer overflow when a user e.g. visits a malicious web site.

Successful exploitation allows execution of arbitrary code.

Solution:
Apply patches.

Windows 98, Windows 98 SE, and Windows Me:
Patches are available from the Windows Update web site.
