The IndexedDatabaseManager class in the IndexedDB implementation in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 misinterprets an unspecified IDBDatabase field as a pointer, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via unspecified vectors, related to a "type confusion" issue. La clase IndexedDatabaseManager en la implementación IndexedDB en Mozilla Firefox anterior a 39.0 y Firefox ESR 31.x anterior a 31.8 y 38.x anterior a 38.1 malinterpreta un campo IDBDatabase no especificado como puntero, lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria y caída de aplicación) a través de vectores no especificados, relacionado con un problema de 'confusión de tipos'. • http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00021.html http://rhn.redhat.com/errata/RHSA-2015-1207.html http://www.debian.org/security/2015/dsa-3300 http://www.mozilla.org/sec • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
