4) Description of Vulnerability

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.
