Descriptions

The get_input_token function in the SPNEGO implementation in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote attackers to cause a denial of service (daemon crash) and possibly obtain sensitive information via a crafted length value that triggers a buffer over-read.

La función get_input_token en la implementación SPNEGO de MIT Kerberos 5 (también conocido como krb5) v1.5 hasta v1.6.3 permite a atacantes remotos provocar una denegación de servicio (caída del demonio) y posiblemente obtener información sensible a través de un valor length modificado que dispara una sobrescritura del búfer.
