Descriptions

The xmlSAX2TextNode function in SAX2.c in the push interface in the HTML parser in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (stack-based buffer over-read and application crash) or obtain sensitive information via crafted XML data.

La función xmlSAX2TextNode en SAX2.c en la interfaz push en el parser HTML en libxml2 en versiones anteriores a 2.9.3 permite a atacantes dependientes del contexto causar una denegación de servicio (sobre lectura de buffer basado en pila y caída de la aplicación) u obtener información sensible a través de datos XML manipulados.

A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to leak potentially sensitive information.
