Mozilla Firefox before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 use the HTTP Host header to determine the context of a document provided in a non-200 CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack. Mozilla Firefox anteriores a v3.0.11, Thunderbird anteriores a v2.0.0.22, y SeaMonkey anteriores a v1.1.17 utilizan la cabecera HTTP del servidor para determinar el contexto de un documento facilitado mediante una respuesta CONNECT no 200 desde un servidor proxy, lo que permite a atacantes "man-in-the-middle" ejecutar secuencias de comandos web arbitrarios mediante la modificación de la respuesta CONNECT, también conocido como ataque "forzado SSL". • http://osvdb.org/55160 http://research.microsoft.com/apps/pubs/default.aspx?id=79323 http://research.microsoft.com/pubs/79323/pbp-final-with-update.pdf http://secunia.com/advisories/35331 http://secunia.com/advisories/35415 http://secunia.com/advisories/35431 http://secunia.com/advisories/35439 http://secunia.com/advisories/35440 http://secunia.com/advisories/35468 http://secunia.com/advisories/35536 http://secunia.com/advisories/35561 http://secunia.com/advisories/35602 • CWE-287: Improper Authentication •

The browser engine in Mozilla Firefox 3 before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) nsEventStateManager::GetContentState and nsNativeTheme::CheckBooleanAttr; (2) UnhookTextRunFromFrames and ClearAllTextRunReferences; (3) nsTextFrame::ClearTextRun; (4) IsPercentageAware; (5) PL_DHashTableFinish; (6) nsListBoxBodyFrame::GetNextItemBox; (7) AtomTableClearEntry, related to the atom table, DOM mutation events, and Unicode surrogates; (8) nsHTMLEditor::HideResizers; and (9) nsWindow::SetCursor, related to changing the cursor; and other vectors. El motor del navegador en Mozilla Firefox v3 anteriores a v3.0.11, Thunderbird anteriores a 2.0.0.22, y SeaMonkey anteriores a 1.1.17 permite a atacantes remotos producir una denegación de servicio (corrupción de memoria y caída de aplicación) o posiblemente ejecutar código arbitrario a través de vectores relacionados con (1) nsEventStateManager::GetContentState y nsNativeTheme::CheckBooleanAttr; (2) UnhookTextRunFromFrames y ClearAllTextRunReferences; (3) nsTextFrame::ClearTextRun; (4) IsPercentageAware; (5) PL_DHashTableFinish; (6) nsListBoxBodyFrame::GetNextItemBox; (7) AtomTableClearEntry, relacionado con la tabla atom, eventos de mutacion DOM, y subrrogados Unicode; (8) nsHTMLEditor::HideResizers; y (9) nsWindow::SetCursor, relacionado con el cambio de cursor; y otros vectores. • http://osvdb.org/55144 http://osvdb.org/55145 http://osvdb.org/55146 http://osvdb.org/55147 http://rhn.redhat.com/errata/RHSA-2009-1096.html http://secunia.com/advisories/35331 http://secunia.com/advisories/35415 http://secunia.com/advisories/35428 http://secunia.com/advisories/35431 http://secunia.com/advisories/35439 http://secunia.com/advisories/35440 http://secunia.com/advisories/35468 http://secunia.com/advisories/35536 http://secunia.com/advisories/3 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

The view-source: URI implementation in Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey does not properly implement the Same Origin Policy, which allows remote attackers to (1) bypass crossdomain.xml restrictions and connect to arbitrary web sites via a Flash file; (2) read, create, or modify Local Shared Objects via a Flash file; or (3) bypass unspecified restrictions and render content via vectors involving a jar: URI. La implementación view-source: URI en Mozilla Firefox anteriores a v3.0.9, Thunderbird, and SeaMonkey no implementa correctamente la política de mismo origen, permitiendo a atacantes remotos (1) saltar las restricciones crossdomain.xml y conectar a sitios web de su elección utilizando un fichero Flash; (2) leer, crear o modificar objetos compartidos locales utilizando un fichero Flash; o (3) saltar restricciones no especificadas y generar contenido mediante vectores relacionados con jar: URI. • http://lists.opensuse.org/opensuse-security-announce/2009-05/msg00000.html http://rhn.redhat.com/errata/RHSA-2009-0437.html http://secunia.com/advisories/34758 http://secunia.com/advisories/34780 http://secunia.com/advisories/34843 http://secunia.com/advisories/34844 http://secunia.com/advisories/34894 http://secunia.com/advisories/35042 http://secunia.com/advisories/35065 http://secunia.com/advisories/35536 http://secunia.com/advisories/35561 http://secunia.com/advisories/3 • CWE-20: Improper Input Validation •

Mozilla Firefox before 3.0.9 and SeaMonkey 1.1.17 do not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header. NOTE: it was later reported that Firefox 3.6 a1 pre and Mozilla 1.7.x and earlier are also affected. Mozilla Firefox anteriores a v3.0.9 y SeaMonkey no bloquean el código "javascript": URIs en cabeceras "Refresh" en respuestas HTTP, permitiendo a atacantes remotos llevar a cabo ataques de secuencias de comandos en sitios cruzados (XSS) utilizando vectores relacinados con (1) inyectar una cabecera "Refresh" o (2) especificar el contenido de una cabecera "Refresh". • https://www.exploit-db.com/exploits/32942 http://ha.ckers.org/blog/20070309/firefox-header-redirection-javascript-execution http://lists.opensuse.org/opensuse-security-announce/2009-05/msg00000.html http://rhn.redhat.com/errata/RHSA-2009-0437.html http://secunia.com/advisories/34758 http://secunia.com/advisories/34843 http://secunia.com/advisories/34844 http://secunia.com/advisories/34894 http://secunia.com/advisories/35065 http://sunsolve.sun.com/search/document.do?assetkey=1-66-2 • CWE-16: Configuration •
