Use-after-free vulnerability in the nsHTMLSelectElement function in nsHTMLSelectElement.cpp in Mozilla Firefox 4.x through 8.0, Thunderbird 5.0 through 8.0, and SeaMonkey before 2.6 allows remote attackers to execute arbitrary code via vectors involving removal of the parent node of an element. Vulnerabilidad de uso después de la liberación en la anterior a v2.6, permite a atacantes remotos ejecutar código arbitrario mediante la vectores que implican la eliminación del nodo padre de un elemento. 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 nsINode::ReplaceOrInsertBefore() in content/base/src/nsGenericElement.cpp. A use-after-free condition can be triggered by adding an already parented option element to an option collection and then removing its associated select element during an event handler execution. • http://www.mozilla.org/security/announce/2012/mfsa2012-41.html https://bugzilla.mozilla.org/show_bug.cgi?id=739343 • CWE-399: Resource Management Errors •
