Mozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2, and SeaMonkey before 2.0.4, frees the contents of the window.navigator.plugins array while a reference to an array element is still active, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors, related to a "dangling pointer vulnerability." El objeto window.navigator.plugins en Mozilla Firefox anteriores a v3.0.19, 3.5.x anteriores a v3.5.9, y v3.6.x anteriores a v3.6.2, y SeaMonkey anteriores a v2.0.4, no gestiona adecuadamente la memoria durante la recarga de una pagina, lo que permite a atacantes remotos ejecutar código de forma arbitraria o producir una denegación de servicio (caída de aplicación) a través de vectores inespecíficos que inician el borrado de objetos referenciados, relacionado con la "vulnerabilidad de puntero colgado". 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 a user must be coerced to viewing a malicious document. The specific flaw exists within the way the application implements the window.navigator.plugins array. Due to the application freeing the contents of the array while a reference to one of the elements is still being used, an attacker can utilize the free reference to call arbitrary code. • 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/39240 http://secunia.com/advisories/39243 http://secunia.com/advisories/39308 http://secunia.com/advisories/39397 http://securitytracker.com/id?1023776 http://ubuntu.com/usn/usn-921-1 http://www.debian.org/security/2010/dsa-2027 http://www.mandriva.com/security&# • CWE-399: Resource Management Errors •

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, possibly before 3.6, allows remote attackers to discover a redirect's target URL, for the session of a specific user of a web site, by placing the site's URL in the HREF attribute of a stylesheet LINK element, and then reading the document.styleSheets[0].href property value, related to an IFRAME element. Mozilla Firefox, probablemente anterior v3.6, permite a atacantes remotos descubrir una redirección de URL, para la sesión de un usuario específico de un sitio web, por sustición de la URL en el atributo HREF de un elemento LINK de una hoja de cálculo, y luego leer el valor de la propiedad document.styleSheets[0].href property, relacionado con un elemento IFRAME. • http://code.google.com/p/chromium/issues/detail?id=32309 http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041383.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041432.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041436.html http://nomoreroot.blogspot.com/2010/01/little-bug-in-safari-and-google-chrome.html https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A12665 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Mozilla Firefox 3.0.x before 3.0.18 and 3.5.x before 3.5.8, and SeaMonkey before 2.0.3, does not properly restrict read access to object properties in showModalDialog, which allows remote attackers to bypass the Same Origin Policy and conduct cross-site scripting (XSS) attacks via crafted dialogArguments values. Mozilla Firefox v3.0.x anterior a la v3.0.18 y v3.5.x anterior a la v3.5.8, y SeaMonkey anterior a la v2.0.3, no restringen de forma adecuada el acceso a las propiedades del objeto en showModalDialog, lo que permite a atacantes remotos saltarse la Same Origin Policy y conducir un ataque de ejecución de secuencias de comandos en sitios cruzados a través de valores manipulados dialogArguments. This vulnerability allows remote attackers to bypass specific script execution enforcements on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the lack of cross domain policy enforcement. Through usage of the showModalDialog() JavaScript method an attacker can gather sensitive information from another website. • http://lists.fedoraproject.org/pipermail/package-announce/2010-February/035346.html http://lists.fedoraproject.org/pipermail/package-announce/2010-February/035367.html http://lists.fedoraproject.org/pipermail/package-announce/2010-February/035426.html http://lists.opensuse.org/opensuse-security-announce/2010-03/msg00001.html http://secunia.com/advisories/37242 http://secunia.com/advisories/38847 http://www.debian.org/security/2010/dsa-1999 http://www.mandriva.com/security/advisories?name=MDVSA-2010:042 • CWE-264: Permissions, Privileges, and Access Controls •
