Vendor:
-------
Adobe Systems Inc. (http://www.adobe.com)
Product web page:

http://www.adobe.com/products/photoshop-elements.html
Affected version:
-----------------
8.0 and 7.0 (20080916r.508356)
Summary:
--------
Adobe Photoshop Elements - the No.1 consumer photo editing software that
helps you turn everyday memories into sensational photos you'll cherish
forever. Easily edit photos and make photo creations using automated

Description:
------------
Photoshop Elements 8 suffers from a buffer overflow vulnerability when
dealing with .ABR (brushes) and .GRD (gradients) format files. The
application fails to sanitize the user input resulting in a memory
corruption, overwriting several memory registers which can aid the
atacker to gain the power of executing arbitrary code on the affected
system or denial of service scenario.
