Posted Sep 3, 2012
Authored by Carsten Eiram | Site secunia.com

Secunia Research has discovered a vulnerability in Adobe Photoshop, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused by insufficient validation in Photoshop.exe when decompressing SGI24LogLum-compressed TIFF images. This can be exploited via a specially crafted TIFF image to cause a heap-based buffer overflow. Successful exploitation may allow execution of arbitrary code.
