Descriptions
MIT Kerberos 5 (aka krb5) 1.7.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read or NULL pointer dereference, and application crash) by injecting invalid tokens into a GSSAPI application session.
MIT Kerberos 5 (también conocido como krb5) 1.7.x hasta 1.12.x anterior a 1.12.2 permite a atacantes remotos causar una denegación de servicio (sobrelectura de buffer o referencia a puntero nulo y caída de aplicación) mediante la inyección de tokens inválidos en una sesión de la aplicación GSSAPI.
A buffer over-read flaw was found in the way MIT Kerberos handled certain requests. A remote, unauthenticated attacker who is able to inject packets into a client or server application's GSSAPI session could use this flaw to crash the application.
