DESCRIPTION:
Walied Assar has discovered a vulnerability in Microsoft Visual
Studio 2008, 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
linker utility (link.exe) when allocating memory based on the number
of COFF symbols. This can be exploited to cause a heap-based buffer
overflow via a specially crafted Portable Executable (PE) file.

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into processing a specially crafted file via
e.g. "dumpbin" or "link /dump" utilities.

The vulnerability is confirmed in version 9.00.21022.08. Other
versions may also be affected.

SOLUTION:
Do not process files from untrusted sources.
