CVE-2013-0754

Vulnerabilidad de uso después de la liberación en la implementación del ListenerManager en Mozilla Firefox anterior a 18.0, Firefox ESR 10.x anterior a 10.0.12 y 17.x anterior a 17.0.2, Thunderbird anterior a 17.0.2, Thunderbird ESR 10.x anterior a 10.0.12 y 17.x anterior a 17.0.2, y SeaMonkey anterior a 2.15, permite a atacantes remotos ejecutar códifo arbitrario a través de vectores que involucran el lanzamiento de colecciones de basura después de una asignación de memoria para los objetos "listener".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. 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 the processing of ListenerManager event listeners. A dangling pointer can be created if a listener frees another listener. By abusing this behavior an attacker can ensure this memory is under control and leverage the situation to achieve remote code execution under the context of the user running the browser.

Multiple vulnerabilities have been found in Mozilla Firefox, Thunderbird, and SeaMonkey, some of which may allow a remote user to execute arbitrary code. Versions less than 17.0.9 are affected.
