Description

This security bulletin contains information about 1 security vulnerability.


1) Stack-based buffer overflow (CVE-ID: CVE-2009-4635)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a crafted MOV container with improperly ordered tags that cause (1) mov.c and (2) utils.c to use inconsistent codec types and identifiers, leading to processing of a video-structure pointer by the mp3 decoder, and a stack-based buffer overflow. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
