The AnimationThread function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 uses an incorrect argument to the sscanf function, which might allow remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via unknown vectors. Vulnerabilidad en la función AnimationThread en Mozilla Firefox en versiones anteriores a 41.0 y Firefox ESR 38.x en versiones anteriores a 38.3, utiliza un argumento incorrecto en la función sscanf, lo que podría permitir a atacantes remotos provocar una denegación de servicio (desbordamiento del buffer basado en pila y caída de la aplicación) o posiblemente tener otro impacto no especificado a través de vectores desconocidos. • http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00025.html http://rhn.redhat.com/errata/RHSA-2015-1834.html http:&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-250: Execution with Unnecessary Privileges •

Mozilla Firefox before 41.0 allows remote attackers to bypass certain ECMAScript 5 (aka ES5) API protection mechanisms and modify immutable properties, and consequently execute arbitrary JavaScript code with chrome privileges, via a crafted web page that does not use ES5 APIs. Vulnerabilidad en Mozilla Firefox en versiones anteriores a 41.0, permite a atacantes remotos eludir ciertos mecanismos de protección de la API ECMAScript 5 (también conocido como ES5) y modificar propiedades inmutables y, consecuentemente, ejecutar código JavaScript arbitario con privilegios de chrome a través de una página web manipulada que no utiliza las APIs ES5. • http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00005.html http://www.mozilla.org/security/announce/2015/mfsa2015-109.html http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/76815 http://www.securitytracker.com/id/1033640 http://www.ubuntu.com/usn/USN-2743-1 http://www.ubuntu.com/usn/USN-2743-2 http://www.ubuntu.com/usn/USN-2743 • CWE-254: 7PK - Security Features •

gfx/2d/DataSurfaceHelpers.cpp in Mozilla Firefox before 41.0 on Linux improperly attempts to use the Cairo library with 32-bit color-depth surface creation followed by 16-bit color-depth surface display, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) by using a CANVAS element to trigger 2D rendering. Vulnerabilidad en gfx/2d/DataSurfaceHelpers.cpp en Mozilla Firefox en versiones anteriores a 41.0 en Linux, intenta utilizar indebidamente la librería Cairo con la creación de 32 bits de profundidad de color seguido por la muestra de 16 bits de profundidad de color de pantalla, lo que permite a atacantes remotos obtener información sensible de memoria de proceso o provocar una denegación de servicio (lectura fuera de rango) mediante el uso de un elemento CANVAS para desencadenar un renderizado 2D. • http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00005.html http://www.mozilla.org/security/announce/2015/mfsa2015-107.html http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/76815 http://www.securitytracker.com/id/1033640 http://www.ubuntu.com/usn/USN-2743-1 http://www.ubuntu.com/usn/USN-2743-2 http://www.ubuntu.com/usn/USN-2743 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Buffer overflow in the vp9_init_context_buffers function in libvpx, as used in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3, allows remote attackers to execute arbitrary code via a crafted VP9 file.
