4) Description of Vulnerability

Secunia Research has discovered a vulnerability in Autodesk SketchBook
Pro, which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error when decompressing
RLE-compressed channel data in PSD files and can be exploited to cause
a heap-based buffer overflow via a specially crafted PSD file.

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into opening a malicious PSD file.
