===============
1) Introduction
===============
Adobe Photoshop is a graphics editing program developed and published by Adobe Systems Incorporated.

Adobe's 2003 "Creative Suite" rebranding led to Adobe Photoshop 8's renaming to Adobe Photoshop CS. Thus,

Adobe Photoshop CS5 is the 12th major release of Adobe Photoshop. The CS rebranding also resulted

in Adobe offering numerous software packages containing multiple Adobe programs for a reduced price.

Adobe Photoshop is released in two editions: Adobe Photoshop, and Adobe Photoshop Extended,

with the Extended having extra 3D image creation, motion graphics editing, and advanced image

analysis features.[3]. Adobe Photoshop Extended is included in all of Adobe's Creative Suite offerings

except Design Standard, which includes the Adobe Photoshop edition.

============================

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations

of Adobe PhotoShop CS5. User interaction is required to exploit this vulnerability in that the

target must open a malicious GIF file. When the "ushort ImageHeight" is crafted with an invalid value

the memory is corrupted and arbitrary code can be run on the remote host.
