Mozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2; Thunderbird before 3.0.4; and SeaMonkey before 2.0.4 do not properly manage reference counts for option elements in a XUL tree optgroup, which might allow remote attackers to execute arbitrary code via unspecified vectors that trigger access to deleted elements, related to a "dangling pointer vulnerability." Mozilla Firefox v3.0.19, v3.5.x antes de v3.5.9, y v3.6.x antes de v3.6.2; Thunderbird antes de v3.0.4, y SeaMonkey antes de v2.0.4 no gestionan adecuadamente la cuenta de referencias a elementos de opción en un árbol XUL optgroup , lo que podría permitir a atacantes remotos ejecutar código arbitrario a través de vectores no especificados que desencadenan el acceso a los elementos eliminados, relacionados con una vulnerabilidad de puntero colgado. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required in that the victim must visit a malicious website or be coerced into opening a malicious document. The specific flaw exists within the way that Mozilla's Firefox parses .XUL files. While appending a particular tag to a treechildren container, the application will create more than one reference to a particular element without increasing its reference count. • http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038367.html http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038378.html http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038406.html http://lists.opensuse.org/opensuse-security-announce/2010-06/msg00001.html http://secunia.com/advisories/38566 http://secunia.com/advisories/39117 http://secunia.com/advisories/39136 http://secunia.com/advisories/39204 http://secunia.com/advisories/39240 http:&# • CWE-399: Resource Management Errors •

Use-after-free vulnerability in the nsTreeSelection implementation in Mozilla Firefox before 3.0.19 and 3.5.x before 3.5.9, Thunderbird before 3.0.4, and SeaMonkey before 2.0.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors that trigger a call to the handler for the select event for XUL tree items. Vulnerabilidad de uso después de la liberación (Use after free)en la implementación nsTreeSelection en Mozilla Firefox anteriores a v3.0.19 y v3.5.x anteriores a v3.5.9, Thunderbird anteriores a v3.0.4, y SeaMonkey anteriores a v2.0.4, permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (caída de la aplicación) a través de vectores no específicos que pueden provocar una llamada a ciertos gestores de de eventos. This vulnerability allows remote attackers to execute arbitrary code on software utilizing a vulnerable version of Mozilla's Firefox. User interaction is required in that the victim must visit a malicious website or be coerced into opening a malicious document. The specific flaw exists within how the application handles particular events for an nsTreeSelection element. Upon execution of a "select" event the application will access an element without checking to see if it's been previously freed or not. • http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038367.html http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038378.html http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038406.html http://lists.opensuse.org/opensuse-security-announce/2010-06/msg00001.html http://secunia.com/advisories/38566 http://secunia.com/advisories/39117 http://secunia.com/advisories/39136 http://secunia.com/advisories/39204 http://secunia.com/advisories/39240 http:&# • CWE-399: Resource Management Errors CWE-416: Use After Free •

Mozilla Firefox 3.0.x before 3.0.18, 3.5.x before 3.5.8, and 3.6.x before 3.6.2; Thunderbird before 3.0.2; and SeaMonkey before 2.0.3 allow remote attackers to perform cross-origin keystroke capture, and possibly conduct cross-site scripting (XSS) attacks, by using the addEventListener and setTimeout functions in conjunction with a wrapped object. NOTE: this vulnerability exists because of an incomplete fix for CVE-2007-3736. Mozilla Firefox v3.0.x anterior a v3.0.18, v3.5.x anterior a v3.5.8 y v3.6.x anterior a v3.6.2; Thunderbird anterior a v3.0.2 y SeaMonkey anterior a v2.0.3 permiten a atacantes remotos realizar capturas de pulsaciones de teclado de origen cruzado y puede que realizar ataques de secuencias de comandos en sitios cruzados (XSS), utilizando las funciones addEventListener y setTimeout junto con un objeto embebido. NOTA: La existencia de esta vulnerabilidad se debe a una incompleta solución de CVE-2007-3736. • http://www.mozilla.org/security/announce/2010/mfsa2010-12.html http://www.securityfocus.com/bid/38918 http://www.vupen.com/english/advisories/2010/0692 https://bugzilla.mozilla.org/show_bug.cgi?id=531364 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A10773 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A7743 https://access.redhat.com/security/cve/CVE-2010-0171 https://bugzilla.redhat.com/show_bug.cgi?id=576696 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
