Descriptions

libxml2 2.7.0 and 2.7.1 does not properly handle "predefined entities definitions" in entities, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash), as demonstrated by use of xmllint on a certain XML document, a different vulnerability than CVE-2003-1564 and CVE-2008-3281.

libxml2 v2.7.0 y v2.7.1 no maneja apropiadamente "definiciones de entidades predefinidas" en entidades, lo cual permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de memoria y caída de aplicación), como lo demostrado por la utilización de xmllint en un determinado documento XML, una vulnerabilidad diferente a CVE-2003-1564 y CVE-2008-3281.
