Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 do not properly initialize nsChildView data structures, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Ogg Vorbis file. Mozilla Firefox v3.6.26 y v4.x hasta el v9.0, Thunderbird antes de v3.1.18 y v5.0 hasta la v9.0 y SeaMonkey antes de v2.7 no inicializa correctamente las estructuras de datos nsChildView, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria caida de la aplicación) o posiblemente ejecutar código de su elección a través de un archivo Ogg Vorbis debidamente manipulado. 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 in the parsing of Ogg Vorbis media files. By crafting a stream with specific values , it is possible to cause a decoding loop that copies memory to write controlled data beyond the end of a fixed size buffer. • http://lists.opensuse.org/opensuse-security-announce/2012-02/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2012-02/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2012-02/msg00011.html http://secunia.com/advisories/48043 http://secunia.com/advisories/48095 http://www.debian.org/security/2012/dsa-2400 http://www.debian.org/security/2012/dsa-2402 http://www.debian.org/security/2012/dsa-2406 http://www.mandriva.com/security/advisories?name=MDVSA- • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Use-after-free vulnerability in Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 might allow remote attackers to execute arbitrary code via vectors related to incorrect AttributeChildRemoved notifications that affect access to removed nsDOMAttribute child nodes. Una vulnerabilidad de uso después de liberaciónen Mozilla Firefox antes de v3.6.26 y v4.x hasta la v9.0, Thunderbird antes de v3.1.18 y v5.0 hasta la v9.0 y SeaMonkey antes de v2.7 podría permitir a atacantes remotos ejecutar código de su elección a través de vectores relacionados con notificaciones AttributeChildRemoved incorrectas que afectan el acceso a nodos hijos nsDOMAttribute. 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 way Firefox handles nsDOMAttribute child removal. It is possible to remove a child without setting the removed child pointer to NULL, thus leaving it still accessible as a dangling pointer. • https://www.exploit-db.com/exploits/18870 http://lists.opensuse.org/opensuse-security-announce/2012-02/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2012-02/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2012-02/msg00011.html http://www.mandriva.com/security/advisories?name=MDVSA-2012:013 http://www.mozilla.org/security/announce/2012/mfsa2012-04.html https://bugzilla.mozilla.org/show_bug.cgi?id=708198 https://oval.cisecurity.org/repository/search/definit • CWE-416: Use After Free •

Mozilla Firefox before 3.6.20, Thunderbird 2.x and 3.x before 3.1.12, SeaMonkey 1.x and 2.x, and possibly other products does not properly handle the RegExp.input property, which allows remote attackers to bypass the Same Origin Policy and read data from a different domain via a crafted web site, possibly related to a use-after-free.
