Mozilla Firefox before 27.0 does not properly restrict access to about:home buttons by script on other pages, which allows user-assisted remote attackers to cause a denial of service (session restore) via a crafted web site. Mozilla Firefox anterior a 27.0 no restringe debidamente el acceso a botones about:home por script en otras páginas, lo que permite a atacantes remotos asistidos por usuario causar una denegación de servicio (restablecimiento de sesión) a través de un sitio web manipulado. • http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00010.html http://osvdb.org/102874 http://secunia.com/advisories/56888 http://www.mozilla.org/security/announce/2014/mfsa2014-10.html http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/65329 http://www.securitytracker.com/id/1029717 http://www.ubuntu.com/usn/USN-2102-1 http://www.ubun • CWE-264: Permissions, Privileges, and Access Controls •

The Content Security Policy (CSP) implementation in Mozilla Firefox before 27.0 and SeaMonkey before 2.24 operates on XSLT stylesheets according to style-src directives instead of script-src directives, which might allow remote attackers to execute arbitrary XSLT code by leveraging insufficient style-src restrictions. La implementación de Content Security Policy (CSP) en Mozilla Firefox anterior a 27.0 y SeaMonkey anterior a 2.24 opera en hojas de estilo XSLT acorde con las directivas style-src en vez de las directivas script-src, lo que permitiría a atacantes remotos ejecutar código XSLT arbitrario mediante el aprovechamiento de las insuficientes restricciones style-src. • http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00017.html http://osvdb.org/102871 http://secunia.com/advisories/56706 http://secunia.com/advisories/56767 http://secunia.com/advisories/56787 http://secunia.com/advisories/56888 http://www.mozilla.org/security/announce/2014/mfsa2014-07.html http://www.oracle.com/technetwork •

RasterImage.cpp in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 does not prevent access to discarded data, which allows remote attackers to execute arbitrary code or cause a denial of service (incorrect write operations) via crafted image data, as demonstrated by Goo Create. RasterImage.cpp en Mozilla Firefox anterior a 27.0, Firefox ESR 24.x anterior a 24.3, Thunderbird anterior a 24.3 y SeaMonkey anterior a 2.24 no previene el acceso a datos descartados, lo que permite a atacantes remotos ejecutar un código arbitrario o causar una denegación de servicio (operaciones de escritura incorrectas) a través de datos de imagen manipulados, como ha demostrado Goo Create. • http://download.novell.com/Download?buildid=VYQsgaFpQ2k http://download.novell.com/Download?buildid=Y2fux-JW1Qc http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127966.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/129218.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00010.html http://lists • CWE-787: Out-of-bounds Write •

Use-after-free vulnerability in the imgRequestProxy function in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 allows remote attackers to execute arbitrary code via vectors involving unspecified Content-Type values for image data. Vulnerabilidad de uso después de liberación en la función imgRequestProxy en Mozilla Firefox anterior a 27.0, Firefox ESR 24.x anterior a 24.3, Thunderbird anterior a 24.3 y SeaMonkey anterior a 2.24 permite a atacantes remotos ejecutar código arbitrario a través de vectores involucrando valores Content-Type no especificados para datos de imagen. 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 handling of imgRequestProxy objects. By manipulating a document's elements an attacker can force a dangling pointer to be reused after it has been freed. • http://download.novell.com/Download?buildid=VYQsgaFpQ2k http://download.novell.com/Download?buildid=Y2fux-JW1Qc http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127966.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/129218.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00010.html http://lists • CWE-416: Use After Free •
