DESCRIPTION:
Francis Provencher has discovered a vulnerability in Adobe Photoshop
CS6, which can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to a boundary error in the "Standard
MultiPlugin.8BF" module when processing a Portable Network Graphics
(PNG) image. This can be exploited to cause a heap-based buffer
overflow via a specially crafted "tRNS" chunk size.

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

The vulnerability is reported in versions 13.x only for Windows and
Macintosh (confirmed in 13.0 20120315.r.428 on Windows).

SOLUTION:
Update to version 13.0.1.

PROVIDED AND/OR DISCOVERED BY:
Francis Provencher via Secunia.
