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 handling layer
bitmap data within PXD files, which can be exploited to cause a
heap-based buffer overflow.

Successful exploitation may allow execution of arbitrary code, but
requires tricking an user into opening specially crafted PXD file.

5) Solution 

Update to version 6.2.6.
