The xmlStringGetNodeList function in tree.c in libxml2 2.9.3 and earlier, when used in recovery mode, allows context-dependent attackers to cause a denial of service (infinite recursion, stack consumption, and application crash) via a crafted XML document. La función xmlStringGetNodeList en tree.c en libxml2.2.9.3 y versiones anteriores, cuando se utiliza en modo de recuperación, permite a atacantes dependientes del contexto provocar una denegación de servicio (bucle infinito, consumo de pila y caída de la aplicación) a través de un docuumento XML manipulado. Missing recursive loop detection checks were found in the xmlParserEntityCheck() and xmlStringGetNodeList() functions of libxml2, causing application using the library to crash by stack exhaustion while building the associated data. An attacker able to send XML data to be parsed in recovery mode could launch a Denial of Service on the application. libxml versions prior to 2.9.3 suffer from a stack overflow vulnerability when parsing a malicious file. • http://lists.opensuse.org/opensuse-updates/2016-05/msg00055.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00127.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://seclists.org/fulldisclosure/2016/May/10 http://www.openwall.com/lists/oss-security/2016/03/21/2 http://www.openwall.com/lists/oss-security/2016/03/21/3 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016& • CWE-674: Uncontrolled Recursion •
