Descriptions

The xmlParseMisc function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (out-of-bounds heap read) via unspecified vectors related to incorrect entities boundaries and start tags.

La función xmlParseMisc en parser.c en libxml2 en versiones anteriores a 2.9.3 permite a atacantes dependientes del contexto causar una denegación de servicio (lectura de memoria dinámica fuera de rango) a través de vectores no especificados relacionados con límites de entidades y etiquetas de inicio incorrectos.

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.
