The SVGTextElement.getCharNumAtPosition function in Mozilla Firefox before 3.6.20, and 4.x through 5; Thunderbird 3.x before 3.1.12 and other versions before 6; SeaMonkey 2.x before 2.3; and possibly other products does not properly handle SVG text, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to a "dangling pointer." La función SVGTextElement.getCharNumAtPosition en Firefox anterior a versión 3.6.20, y versiones 4.x hasta 5; Thunderbird versiones 3.x anteriores a 3.1.12 y otras versiones anteriores a 6; SeaMonkey versiones 2.x anteriores a 2.3; y posiblemente otros productos de Mozilla, no maneja apropiadamente el texto SVG, lo que permite a los atacantes remotos ejecutar código arbitrario por medio de vectores no especificados que conlleva a un "dangling pointer" 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 code responsible for parsing SVG text containers. The code within nsSVGGlyphFrame::GetCharNumAtPosition() does not account for user defined getter methods modifying or destroying the parent object. An attacker can abuse this flaw to create a dangling pointer which is referenced during the traversal of the SVG container hierarchy. • http://lists.opensuse.org/opensuse-security-announce/2011-08/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2011-08/msg00027.html http://www.debian.org/security/2011/dsa-2295 http://www.debian.org/security/2011/dsa-2296 http://www.debian.org/security/2011/dsa-2297 http://www.mandriva.com/security/advisories?name=MDVSA-2011:127 http://www.mozilla.org/security/announce/2011/mfsa2011-29.html http://www.mozilla.org/security/announce/2011/mfsa2011-30.html http:/& • CWE-94: Improper Control of Generation of Code ('Code Injection') •

Mozilla Firefox before 4 cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue. Mozilla Firefox en versiones anteriores a la versión 4 no restringe apropiadamente las modificaciones a las cookies establecidas en las sesiones HTTPS, lo que facilita a atacantes "man-in-the-middle" sobreescribir o borrar cookies arbitrarias a través de una cabecera Set-Cookie en una respuesta HTTP, relacionado con una fallo en la funcionalidad HTTP Strict Transport Security (HSTS) includeSubDomains. También conocido como un problema "cookie forcing". • http://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_cookies http://hacks.mozilla.org/2010/08/firefox-4-http-strict-transport-security-force-https http://michael-coates.blogspot.com/2010/01/cookie-forcing-trust-your-cookies-no.html http://scarybeastsecurity.blogspot.com/2008/11/cookie-forcing.html http://scarybeastsecurity.blogspot.com/2011/02/some-less-obvious-benefits-of-hsts.html https://bugzilla.mozilla.org/show_bug.cgi?id=660053 • CWE-264: Permissions, Privileges, and Access Controls •

CRLF injection vulnerability in the nsCookieService::SetCookieStringInternal function in netwerk/cookie/nsCookieService.cpp in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, and Thunderbird before 3.1.11, allows remote attackers to bypass intended access restrictions via a string containing a \n (newline) character, which is not properly handled in a JavaScript "document.cookie =" expression, a different vulnerability than CVE-2011-2374. Inyección CRLF en la función nsCookieService::SetCookieStringInternal en netwerk/cookie/nsCookieService.cpp de Mozilla Firefox antes de v3.6.18 y v4.x hasta 4.0.1 y Thunderbird antes de v3.1.11, permite a atacantes remotos evitar las restricciones de acceso a través de una cadena que contiene un carácter \n (nueva línea) , que no se maneja en una expresion "document.cookie =" de JavaScript es una vulnerabilidad diferente a CVE-2011-2374. • http://www.mozilla.org/security/announce/2011/mfsa2011-19.html http://www.redhat.com/support/errata/RHSA-2011-0885.html http://www.redhat.com/support/errata/RHSA-2011-0886.html http://www.redhat.com/support/errata/RHSA-2011-0887.html http://www.redhat.com/support/errata/RHSA-2011-0888.html https://bugzilla.mozilla.org/show_bug.cgi?id=643051 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A14401 https://access.redhat.com/security/cve/CVE-2 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

Mozilla Gecko before 5.0, as used in Firefox before 5.0 and Thunderbird before 5.0, does not block use of a cross-domain image as a WebGL texture, which allows remote attackers to obtain approximate copies of arbitrary images via a timing attack involving a crafted WebGL fragment shader. Mozilla Gecko usado en Firefox v5.0 y Thunderbird antes de v5.0, no bloquea el uso de una imagen como textura WebGL en dominios cruzados, lo que permite a atacantes remotos obtener copias aproximadas de imágenes arbitrarias mediante un ataque de temporizacion mediante la participación de un fragmento sombreado manipulado en WebGL. • http://lists.opensuse.org/opensuse-security-announce/2011-07/msg00001.html http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2011-March/030882.html http://www.contextis.co.uk/resources/blog/webgl http://www.mozilla.org/security/announce/2011/mfsa2011-25.html https://bugzilla.mozilla.org/show_bug.cgi?id=655987 https://bugzilla.mozilla.org/show_bug.cgi?id=656277 https://bugzilla.mozilla.org/show_bug.cgi?id=659349 https://developer.mozilla.org/en/WebGL/Cross-Domain_Textures https: • CWE-20: Improper Input Validation •
