The nsIScriptableUnescapeHTML.parseFragment method in the ParanoidFragmentSink protection mechanism in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 does not properly sanitize HTML in a chrome document, which makes it easier for remote attackers to execute arbitrary JavaScript with chrome privileges via a javascript: URI in input to an extension, as demonstrated by a javascript:alert sequence in (1) the HREF attribute of an A element or (2) the ACTION attribute of a FORM element. El método nsIScriptableUnescapeHTML.parseFragment en el mecanismo de protección ParanoidFragmentSink en Mozilla Firefox en versiones anteriores a 3.5.17 y 3.6.x en versiones anteriores a 3.6.14, Thunderbird en versiones anteriores a 3.1.8 y SeaMonkey en versiones anteriores a 2.0.12 no desinfecta adecuadamente HTML en un documento chrome, lo que hace más fácil a atacantes remotos ejecutar JavaScript arbitrario con privilegios de chrome a través de un javascript: URI en entrada a una extensión, como se demuestra por una secuencia javascript:alert en el atributo (1) HREF de un elemento A o el atributo (2) ACTION de un elemento FORM. • http://downloads.avaya.com/css/P8/documents/100133195 http://wizzrss.blat.co.za/2009/11/17/so-much-for-nsiscriptableunescapehtmlparsefragment http://www.mandriva.com/security/advisories?name=MDVSA-2011:041 http://www.mandriva.com/security/advisories?name=MDVSA-2011:042 http://www.mozilla.org/security/announce/2011/mfsa2011-08.html http://www.security-assessment.com/files/whitepapers/Cross_Context_Scripting_with_Firefox.pdf http://www.securityfocus.com/archive/1/510883/100/0/threaded https://bug • CWE-20: Improper Input Validation •

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.5.9 and 3.6.x before 3.6.2, Thunderbird before 3.0.4, and SeaMonkey before 2.0.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox before 3.0.19 and 3.5.x before 3.5.8, and SeaMonkey before 2.0.3, when the XMLHttpRequestSpy module in the Firebug add-on is used, does not properly handle interaction between the XMLHttpRequestSpy object and chrome privileged objects, which allows remote attackers to execute arbitrary JavaScript via a crafted HTTP response. Mozilla Firefox anteriores a v3.0.19 y v3.5.x anteriores a v3.5.8, y SeaMonkey anteriores a v2.0.3, cuando se utiliza el modulo XMLHttpRequestSpy en el complemento Firebug, no gestiona adecuadamente la interacción entre el objeto XMLHttpRequestSpy y los objetos con privilegios chrome, lo que permite a atacantes remotos ejecutar JavaScript de forma arbitraria a través de peticiones HTTP manipuladas. • http://lists.opensuse.org/opensuse-security-announce/2010-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00002.html http://secunia.com/advisories/3924 http://secunia.com/advisories/39243 http://secunia.com/advisories/39308 http://secunia.com/advisories/39397 http://secunia.com/advisories/42818 http://securitytracker.com/id?1023783 http://support.avaya.com/css/P8/documents/100124650 http://ubuntu.com/usn/usn-921-1 http://www.debian.org/security& • CWE-94: Improper Control of Generation of Code ('Code Injection') •

The XMLDocument::load function in Mozilla Firefox before 3.5.9 and 3.6.x before 3.6.2, Thunderbird before 3.0.4, and SeaMonkey before 2.0.4 does not perform the expected nsIContentPolicy checks during loading of content by XML documents, which allows attackers to bypass intended access restrictions via crafted content.
