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

The vulnerability is caused due to a boundary error in the
"UpdateFrameTitleForDocument()" function of the CFrameWnd class in
mfc42.dll. This can be exploited to cause a stack-based buffer
overflow by passing an overly long title string argument to the
affected function.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in fully patched versions of Windows
2000 Professional SP4 including mfc42.dll version 6.0.9586.0 and
Windows XP SP2/SP3 including mfc42.dll version 6.2.4131.0. Other
versions may also be affected.

The following products are currently known to present valid attack
vectors:
* PowerZip version 7.2 Build 4010 (when e.g. entering an overly long
directory in an opened archive).

Other versions and applications using the vulnerable library may also
be affected.

SOLUTION:
Restrict access to applications allowing user-controlled input to be
passed to the vulnerable function.

PROVIDED AND/OR DISCOVERED BY:
Originally reported in PowerZip by fl0 fl0w.
