Descriptions

The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing.

Vulnerabilidad en la función "kg_accept_krb5" en "krb5/accept_sec_context.c" de la librería GSS-API en MIT Kerberos v5 (también conocido como krb5) a través de v1.7.1 y v1.8 anterior a v1.8.2, como los usados en "kadmind" y otras aplicaciones, no comprueban adecuadamente vales (tokens) GSS-API inválidos, que permiten a usuarios autenticados remotamente causar una denegación de servicio (referencia a puntero nulo y caída del demonio) a través de un mensaje AP-REQ en el cual se pierde el campo "checksum" del usuario autenticado.
