CVE-2011-0596

Adobe Reader y Acrobat v10.x anterior a v10.0.1, v9.x anterior a v9.4.2, y v8.x anterior a v8.2.6 en Windows y Mac OS X permite a atacantes remotos ejecutar código de su elección a través de una imagen, una vulnerabilidad diferente de CVE-2011-0598, CVE-2011-0599, y CVE-2011-0602.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The flaw exists within the Bitmap parsing component of 2d.dll. When allocating a destination buffer for handling RLE_8 compressed bitmaps the process uses the bitmap height and width values directly. Certain assumptions are made regarding minimum values of these fields during decompression resulting in a copy user supplied data into a fixed-length buffer on the heap. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the user.
