Mozilla Firefox before 3.6.7 and Thunderbird before 3.1.1 do not properly implement read restrictions for CANVAS elements, which allows remote attackers to obtain sensitive cross-origin information via vectors involving reference retention and node deletion. Mozilla Firefox en versiones anteriores a la v3.6.7 y Thunderbird en versiones anteriores a la v3.1.1 no implementan apropiadamente las restricciones de acceso a los elementos CANVAS, lo que permite a atacantes remotos obtener información confidencial fuera de origen a través de vectores de ataque relacionados con la retención de referencias y el borrado de nodos. • http://www.mozilla.org/security/announce/2010/mfsa2010-43.html https://bugzilla.mozilla.org/show_bug.cgi?id=571287 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11887 https://access.redhat.com/security/cve/CVE-2010-1207 https://bugzilla.redhat.com/show_bug.cgi?id=615472 • CWE-264: Permissions, Privileges, and Access Controls •

Integer overflow in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, and SeaMonkey before 2.0.6, allows remote attackers to execute arbitrary code via plugin content with many parameter elements. Desbordamiento de entero en Mozilla Firefox v3.5.x anteriores a la v3.5.11 y v3.6.x anteriores a la v3.6.7, y SeaMonkey en versiones anteriores a la v2.0.6, permite a atacantes remotos ejecutar código de elección a través del "plugin content" con muchos elementos de parámetro. 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 browser's method for parsing child elements out of a particular tag. The application will use a 32-bit index to enumerate them, but will store it in a 16-bit signed integer and then use it to allocate space for a cache. • https://www.exploit-db.com/exploits/34358 https://www.exploit-db.com/exploits/15027 http://www.mozilla.org/security/announce/2010/mfsa2010-37.html https://bugzilla.mozilla.org/show_bug.cgi?id=572985 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11685 https://access.redhat.com/security/cve/CVE-2010-1214 https://bugzilla.redhat.com/show_bug.cgi?id=615462 • CWE-189: Numeric Errors •

Integer overflow in an array class in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 allows remote attackers to execute arbitrary code by placing many Cascading Style Sheets (CSS) values in an array, related to references to external font resources and an inconsistency between 16-bit and 32-bit integers. Un desbordamiento de enteros en una clase de matriz en Firefox versiones 3.5.x anteriores a 3.5.11 y versiones 3.6.x anteriores a 3.6.7, Thunderbird versiones 3.0.x anteriores a 3.0.6 y versiones 3.1.x anteriores a 3.1.1, y SeaMonkey anterior a versión 2.0.6, de Mozilla, permite a los atacantes remotos ejecutar código arbitrario mediante la colocación de muchos valores de Cascading Style Sheets (CSS) en una matriz, relacionada con referencias a recursos de fuente externa y una inconsistencia entre enteros de 16 bits y 32 bits. 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 handling of references to external font resources. A value is used as a 16 bit integer in an array allocation and later as 32 bit when iterating over and then populating these fields. • https://www.exploit-db.com/exploits/15104 http://www.mozilla.org/security/announce/2010/mfsa2010-39.html http://www.securityfocus.com/archive/1/512514 http://www.securityfocus.com/bid/41852 http://www.zerodayinitiative.com/advisories/ZDI-10-133 https://bugzilla.mozilla.org/show_bug.cgi?id=574059 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11680 https://access.redhat.com/security/cve/CVE-2010-2752 https://bugzilla.redhat.com/show_bug.cgi? • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •

Integer overflow in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 allows remote attackers to execute arbitrary code via a large selection attribute in a XUL tree element, which triggers a use-after-free. Un desbordamiento de enteros en Firefox versiones 3.5.x anteriores a 3.5.11 y versiones 3.6.x anteriores a 3.6.7, Thunderbird versiones 3.0.x anteriores a 3.0.6 y versiones 3.1.x anteriores a 3.1.1, y SeaMonkey anterior a versión 2.0.6, de Mozilla, permite a atacantes remotos ejecutar código arbitrario por medio de un atributo de selección grande en un elemento del árbol XUL, lo que desencadena un uso de la memoria previamente liberada. 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 implementation of XUL <tree> element's "selection" attribute. There is an integer overflow when calculating the bounds of a new selection range. • http://lists.opensuse.org/opensuse-security-announce/2010-10/msg00002.html http://www.mozilla.org/security/announce/2010/mfsa2010-40.html http://www.securityfocus.com/archive/1/512510 http://www.securityfocus.com/bid/41853 http://www.zerodayinitiative.com/advisories/ZDI-10-131 https://bugzilla.mozilla.org/show_bug.cgi?id=571106 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A10958 https://access.redhat.com/security/cve/CVE-2010-2753 https://bugzilla • CWE-190: Integer Overflow or Wraparound CWE-416: Use After Free •

Use-after-free vulnerability in the attribute-cloning functionality in the DOM implementation in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, and SeaMonkey before 2.0.6, allows remote attackers to execute arbitrary code via vectors related to deletion of an event attribute node with a nonzero reference count. Una vulnerabilidad de uso de la memoria previamente liberada en la funcionalidad de clonación de atributos en la implementación DOM en Firefox versiones 3.5.x anteriores a 3.5.11 y versiones a 3.6.x anteriores a 3.6.7, y SeaMonkey anterior a versión 2.0.6, de Mozilla, permite a los atacantes remotos ejecutar código arbitrario por medio de vectores relacionados a la eliminación de un nodo de atributo de evento con un conteo de referencia diferente de cero. 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 due to a workaround that was implemented in order to support recursive cloning of attribute nodes. If an event is added to the first attribute node, the application can be made to free the node, and then later access a reference to it. • http://www.mozilla.org/security/announce/2010/mfsa2010-35.html http://www.securityfocus.com/archive/1/512515 http://www.securityfocus.com/bid/41849 http://www.zerodayinitiative.com/advisories/ZDI-10-134 https://bugzilla.mozilla.org/show_bug.cgi?id=572986 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11740 https://access.redhat.com/security/cve/CVE-2010-1208 https://bugzilla.redhat.com/show_bug.cgi?id=615458 • CWE-416: Use After Free •
