Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions. Desbordamiento de entero en xpath.c en libxml2 v2.6.x hasta v2.6.32 y v2.7.x hasta v2.7.8, y libxml v1.8.16 y anteriores, permite a atacantes dependientes del contexto, provocar una denegación de servicio (caída) y posiblemente ejecutar código de su elección a través de un archivo XML modificado que provoca un desbordamiento de buffer basado en memoria dinámica cuando se añade un nuevo espacio de nombres al nodo, relacionado con la manipulación de expresiones XPath. • https://www.exploit-db.com/exploits/35810 http://git.gnome.org/browse/libxml2/commit/?id=d7958b21e7f8c447a26bb2436f08402b2c308be4 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03360041 http://lists.apple.com/archives/security-announce/2012/May/msg00001.html http://lists.apple.com/archives/security-announce/2012/Sep/msg00003.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062238.html http://lists.opensuse.org/opensuse-updates/2011-07/msg00035.html http:/ • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •
