DESCRIPTION:
rgod has discovered a vulnerability in Microsoft Windows, which can
be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an input validation error in the
Windows Fax Cover Page Editor component (fxscover.exe) when the
"CDrawPoly::Serialize()" function reads in data from a Fax Cover Page
file (".cov"). This can be exploited to cause a heap-based buffer
overflow via a Fax Cover Page file containing specially crafted
content.

Successful exploitation allows execution of arbitrary code, but
requires that "Fax Services" / "Windows Fax and Scan" is installed.

The vulnerability is confirmed in fully patched versions of Windows
XP Professional SP3, Windows Server 2003 R2 Enterprise Edition SP2,
and Windows 7 Professional. Other versions may also be affected.

SOLUTION:
Do not open untrusted Fax Cover Page files.
