CVE-2016-1521 – graphite2: Out-of-bound read vulnerability triggered by crafted fonts

https://notcve.org/view.php?id=CVE-2016-1521

The directrun function in directmachine.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, does not validate a certain skip operation, which allows remote attackers to execute arbitrary code, obtain sensitive information, or cause a denial of service (out-of-bounds read and application crash) via a crafted Graphite smart font. La función directmachine.cpp en Libgraphite en Graphite 2 1.2.4, como se utiliza en Mozilla Firefox en versiones anteriores a 43.0 y Firefox ESR 38.x en versiones anteriores a 38.6.1, no valida una determinada operación de salto, lo que permite a atacantes remotos ejecutar código arbitrario, obtener información sensible o causar una denegación de servicio (lectura fuera de rango y caída de aplicación) a través de una fuente inteligente Graphite. A vulnerability has been discovered in Graphite2. An attacker able to trick an unsuspecting user into opening specially crafted font files in an application using Graphite2 could exploit these flaws to cause the application to crash or, potentially, execute arbitrary code with the privileges of the application. • http://blog.talosintel.com/2016/02/vulnerability-spotlight-libgraphite.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177520.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184623.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00088.html http://rhn.redhat.com/errata/RHSA-2016-0197.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
