https://notcve.org/view.php?id=CVE-2016-5277

Use-after-free vulnerability in the nsRefreshDriver::Tick function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) by leveraging improper interaction between timeline destruction and the Web Animations model implementation. Vulnerabilidad de uso de memoria previamente liberada en la función nsRefreshDriver::Tick en Mozilla Firefox en versiones anteriores a la 49.0, Firefox ESR en versiones 45.x anteriores a la 45.4 y Thunderbird en versiones anteriores a la 45.4 permite que los atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (corrupción de memoria dinámica o heap) utilizando la interacción errónea entre timeline destruction y la implementación del modelo Web Animations. • http://rhn.redhat.com/errata/RHSA-2016-1912.html http://www.debian.org/security/2016/dsa-3674 http://www.mozilla.org/security/announce/2016/mfsa2016-85.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93049 http://www.securitytracker.com/id/1036852 https://bugzilla.mozilla.org/show_bug.cgi?id=1291665 https://security.gentoo.org/glsa/201701-15 https://www.mozilla.org/security/advisories/mfsa2016-86 https:// • CWE-416: Use After Free •

CVE-2016-5284 – Mozilla: Add-on update site certificate pin expiration (MFSA 2016-85, MFSA 2016-86)

https://notcve.org/view.php?id=CVE-2016-5284

Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 rely on unintended expiration dates for Preloaded Public Key Pinning, which allows man-in-the-middle attackers to spoof add-on updates by leveraging possession of an X.509 server certificate for addons.mozilla.org signed by an arbitrary built-in Certification Authority. Mozilla Firefox en versiones anteriores a la 49.0, Firefox ESR en versiones 45.x anteriores a la 45.4 y Thunderbird en versiones anteriores a la 45.4 confían en fechas de expiración erróneas para Preloaded Public Key Pinning, lo que permite a los atacantes Man-in-the-Middle (MitM) suplantar las actualizaciones de los add-ons aprovechando la posesión de un certificado de servidor X.509 para addons.mozilla.org firmado por una autoridad certificadora integrada arbitraria. • http://rhn.redhat.com/errata/RHSA-2016-1912.html http://seclists.org/dailydave/2016/q3/51 http://www.debian.org/security/2016/dsa-3674 http://www.mozilla.org/security/announce/2016/mfsa2016-85.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93049 http://www.securitytracker.com/id/1036852 https://blog.mozilla.org/security/2016/09/16/update-on-add-on-pinning-vulnerability https://bugzilla.mozilla.org/show_bu • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2016-5270

Heap-based buffer overflow in the nsCaseTransformTextRunFactory::TransformString function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to cause a denial of service (boolean out-of-bounds write) or possibly have unspecified other impact via Unicode characters that are mishandled during text conversion. Desbordamiento de búfer basado en memoria dinámica (heap) en la función nsCaseTransformTextRunFactory::TransformString en Mozilla Firefox en versiones anteriores a la 49.0, Firefox ESR en versiones 45.x anteriores a la 45.4 y Thunderbird en versiones anteriores a la 45.4 permite que los atacantes remotos provoquen una denegación de servicio (escritura de valores boleanos fuera de límites) o, posiblemente, provocar otro impacto no especificado mediante caracteres unicode que se manejan incorrectamente durante la conversión de texto. • http://rhn.redhat.com/errata/RHSA-2016-1912.html http://www.debian.org/security/2016/dsa-3674 http://www.mozilla.org/security/announce/2016/mfsa2016-85.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93049 http://www.securitytracker.com/id/1036852 https://bugzilla.mozilla.org/show_bug.cgi?id=1291016 https://security.gentoo.org/glsa/201701-15 https://www.mozilla.org/security/advisories/mfsa2016-86 https:// • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

CVE-2016-2839

https://notcve.org/view.php?id=CVE-2016-2839

Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 on Linux make cairo _cairo_surface_get_extents calls that do not properly interact with libav header allocation in FFmpeg 0.10, which allows remote attackers to cause a denial of service (application crash) via a crafted video. Mozilla Firefox en versiones anteriores a 48.0 y Firefox ESR 45.x en versiones anteriores a 45.3 en Linux hace llamadas cairo _cairo_surface_get_extents que no interactúan adecuadamente con asignación de cabecera libav en FFmpeg 0.10, lo que permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un vídeo manipulado. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00029.html http://www.mozilla.org/security/announce/2016/mfsa2016-65.html http://www.securityfocus.com/bid/92261 http://www.securitytracker.com/id/1036508 http://www.ubuntu.com/usn/USN-3044-1 https://bugzilla.mozilla.org/show_bug.cgi?id=1275339 https://security.gentoo.org/glsa/201701-15 • CWE-20: Improper Input Validation •
