DESCRIPTION:
A weakness has been reported in Microsoft Windows, which can be
exploited by malicious people to bypass certain security features.

The weakness is caused due an error in the way the kernel (ntdll.dll)
loads structured exception handling tables and allows bypassing the
SafeSEH security mechanism. This facilitates easier exploitation of
other vulnerabilities in affected applications to execute code.

NOTE: The weakness only affects applications compiled using Microsoft
Visual C++ .NET 2003.

SOLUTION:
Apply patches.
