The Web Worker functionality in Mozilla Firefox 3.0.x before 3.0.18 and 3.5.x before 3.5.8, and SeaMonkey before 2.0.3, does not properly handle array data types for posted messages, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors. La funcionalidad Web Worker en Mozilla Firefox v3.0.x anterior a la v3.0.18 y 3.5.x anterior a la v3.5.8, y SeaMonkey anteriores a la v2.0.3, no manejan de forma adecuada los tipos de datos array para mensajes posteado, lo que permite que atacantes remotos provoquen una denegación de servicio (corrupción de memoria dinámica y caída de la aplicación) o posiblemente ejecución de código de su elección a través de vectores no especificados. 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. The specific flaw exists within the implementation of web worker threads. Due to mishandling the array data type while processing posted messages, a web worker thread can be made to corrupt heap memory. • http://lists.fedoraproject.org/pipermail/package-announce/2010-February/035346.html http://lists.fedoraproject.org/pipermail/package-announce/2010-February/035367.html http://lists.fedoraproject.org/pipermail/package-announce/2010-February/035426.html http://lists.opensuse.org/opensuse-security-announce/2010-03/msg00001.html http://secunia.com/advisories/37242 http://secunia.com/advisories/38847 http://www.debian.org/security/2010/dsa-1999 http://www.mandriva.com/security/advisories?name=MDVSA-2010:042 • CWE-399: Resource Management Errors •

The nsObserverList::FillObserverArray function in xpcom/ds/nsObserverList.cpp in Mozilla Firefox before 3.5.7 allows remote attackers to cause a denial of service (application crash) via a crafted web site that triggers memory consumption and an accompanying Low Memory alert dialog, and also triggers attempted removal of an observer from an empty observers array. La función nsObserverList::FillObserverArray en xpcom/ds/nsObserverList.cpp en Mozilla Firefox anterior a v3.5.7 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un sitio web manipulado que provoca consumo de memoria y un dialogo de alerta de memoria baja, y también provoca un intento de borrado de un observador desde una matriz de observadores vacío. • http://hg.mozilla.org/mozilla-central/rev/51396f6c9f20 http://isc.sans.org/diary.html?storyid=7897 http://www.mandriva.com/security/advisories?name=MDVSA-2010:000 http://www.mozilla.com/en-US/firefox/3.5.7/releasenotes https://bugzilla.mozilla.org/show_bug.cgi?id=507114 https://exchange.xforce.ibmcloud.com/vulnerabilities/55550 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A8292 • CWE-399: Resource Management Errors •

The GeckoActiveXObject function in Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, generates different exception messages depending on whether the referenced COM object is listed in the registry, which allows remote attackers to obtain potentially sensitive information about installed software by making multiple calls that specify the ProgID values of different COM objects. La función GeckoActiveXObject en Mozilla Firefox antes de v3.0.16 y v3.5.x antes de v3.5.6, y SeaMonkey antes de v2.0.1, genera mensajes de excepción diferentes dependiendo de si el objeto COM al que se hace referencia aparece en el registro, lo que permite obtener a atacantes remotos, información potencialmente confidencial sobre el software instalado. Esto se consigue haciendo multiples llamadas que especifican los valores de ProgID de diferentes objetos COM. • http://secunia.com/advisories/37699 http://secunia.com/advisories/37785 http://securitytracker.com/id?1023346 http://securitytracker.com/id?1023347 http://www.mozilla.org/security/announce/2009/mfsa2009-71.html http://www.securityfocus.com/bid/37349 http://www.securityfocus.com/bid/37360 http://www.vupen.com/english/advisories/2009/3547 https://bugzilla.mozilla.org/show_bug.cgi?id=503451 https://bugzilla.redhat.com/show_bug.cgi?id=546729 https://exchange.xforce.ibmcloud.com • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
