Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, Thunderbird before 3.0.11 and 3.1.x before 3.1.7, and SeaMonkey before 2.0.11 do not properly validate downloadable fonts before use within an operating system's font implementation, which allows remote attackers to execute arbitrary code via vectors related to @font-face Cascading Style Sheets (CSS) rules. Mozilla Firefox en versiones anteriores a la 3.5.16 y 3.6.x en versiones anteriores a la 3.6.13, Thunderbird en versiones anteriores a la 3.0.11 y 3.1.x en versiones anteriores a la 3.1.7 y SeaMonkey en versiones anteriores a la 2.0.11 no validan de manera apropiada las fuentes que se pueden descargar antes de usarlas en una implementación de fuentes del sistema operativo, lo que permite a atacantes remotos ejecutar código de su elección mediante vectores relacionados con reglas @font-face Cascading Style Sheets (CSS). • http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052022.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052032.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052110.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052220.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052502.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052504.html http://lists.opensuse.org& • CWE-20: Improper Input Validation •

Integer overflow in the NewIdArray function in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, allows remote attackers to execute arbitrary code via a JavaScript array with many elements. Desbordamiento de entero en la función NewArray en Mozilla Firefox en versiones anteriores a la 3.5.16 y 3.6.x en versiones anteriores a la 3.6.13 y SeaMonkey en versiones anteriores a la 2.0.11, permite a atacantes remotos ejecutar código de su elección mediante un array JavaScript con muchos elementos. 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 Firefox's management of the JSSLOT_ARRAY_COUNT annotation. • http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052022.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052032.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052502.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052504.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00002.html http://secunia.com/advisories/42716 http://secunia.com/advisories/42818 http://support.avaya.com/css/P8& • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •

Mozilla Firefox 3.5.x through 3.5.14 and 3.6.x through 3.6.11, Thunderbird 3.1.6 before 3.1.6 and 3.0.x before 3.0.10, and SeaMonkey 2.x before 2.0.10, when JavaScript is enabled, allows remote attackers to execute arbitrary code via vectors related to nsCSSFrameConstructor::ContentAppended, the appendChild method, incorrect index tracking, and the creation of multiple frames, which triggers memory corruption, as exploited in the wild in October 2010 by the Belmoo malware. Firefox versiones 3.5.x hasta 3.5.14 y versiones 3.6.x hasta 3.6.11, Thunderbird versiones 3.1.6 anteriores a 3.1.6 y versiones 3.0.x anteriores a 3.0.10, y SeaMonkey versiones 2.x anteriores a 2.0.10, de Mozilla, cuando JavaScript está habilitado, permite a los atacantes remotos ejecutar código arbitrario por medio de vectores relacionados con nsCSSFrameConstructor::ContentAppended, el método appendChild, el seguimiento incorrecto de índices y la creación de varias tramas, lo que desencadena corrupción de memoria, como se explotó “in the wild” en octubre de 2010 por el malware Belmoo. • https://www.exploit-db.com/exploits/15342 https://www.exploit-db.com/exploits/15341 https://www.exploit-db.com/exploits/16509 https://www.exploit-db.com/exploits/15352 http://blog.mozilla.com/security/2010/10/26/critical-vulnerability-in-firefox-3-5-and-firefox-3-6 http://blogs.sun.com/security/entry/multiple_vulnerabilities_in_mozilla_firefox http://isc.sans.edu/diary.html? • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
