Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly handle injection of an ISINDEX element into an about:blank page, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges via vectors related to redirection to a chrome: URI. 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, no manejan de manera apropiada la inyección de un elemento ISINDEX en una página about:blank, lo que permite a atacantes remotos ejecutar código JvaScript de su elección con privilegios chrome mediante vectores relacionados con una redirección a una URI chrome: • 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& •

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 •

Use-after-free vulnerability 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 vectors involving a change to an nsDOMAttribute node. Vulnerabilidad de uso después de liberación 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 vectores que involucran un cambio a un nodo 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 application's support of the NodeIterator API used for element traversal. Due to a particular element not implementing functionality required by the API, a use-after free vulnerability can be forced to occur. • 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-399: Resource Management Errors CWE-416: Use After Free •

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. This value represents the number of items filled within a given Array object. • 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 •
