Descriptions
The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660.
La función xmlStringLenDecodeEntities en parser.c en libxml2 en versiones anteriores a 2.9.3 no previene adecuadamente la expansión de entidad, lo que permite a atacantes dependientes del contexto causar una denegación de servicio (consumo de CPU) a través de datos XML manipulados, una vulnerabilidad diferente a CVE-2014-3660.
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 use an excessive amount of CPU.
