Descriptions

Heap-based buffer overflow in the xmlParseXmlDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service via unspecified vectors related to extracting errors after an encoding conversion failure.

Desbordamiento de buffer basado en memoria dinámica en la función xmlParseXmlDecl en parser.c en libxml2 en versiones anteriores a 2.9.3 permite a atacantes dependientes del contexto causar una denegación de servicio a través de vectores no especificados relacionados con errores de extracción después de un fallo de conversión de la codificación.

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 crash.
