CVE-2011-4373

Adobe Reader y Adobe Acrobat antes de v9.5, y v10.x antes de v10.1.2, en Windows y Mac OS X permite a los atacantes ejecutar código de su elección o causar una denegación de servicio (por corrupción de memoria) a través de vectores no especificados. Se trata de una vulnerabilidad diferente a CVE-2011-4370 y CVE-2011-4372.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Reader X. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within 2d.x3d, which is Adobe Reader's code responsible for processing BMP files. When passing a negative size parameter in the 'colors' field, a series of signed comparisons will be averted, and the overly large size parameter is passed to a memcpy(). This will cause a heap-based buffer overflow, allowing an attacker to execute code under the context of the user.
