Descriptions

The xmlNextChar function in libxml2 2.9.2 does not properly check the state, which allows context-dependent attackers to cause a denial of service (heap-based buffer over-read and application crash) or obtain sensitive information via crafted XML data.

La función xmlNextChar en libxml2 2.9.2 no comprueba correctamente el estado, lo que permite a atacantes dependientes del contexto causar una denegación de servicio (sobre lectura de buffer basado en memoria dinámica 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.
