Descriptions

The merge_authdata function in kdc_authdata.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8.x before 1.8.4 does not properly manage an index into an authorization-data list, which allows remote attackers to cause a denial of service (daemon crash), or possibly obtain sensitive information, spoof authorization, or execute arbitrary code, via a TGS request that triggers an uninitialized pointer dereference, as demonstrated by a request from a Windows Active Directory client.

La función merge_authdata en kdc_authdata.c en el Key Distribution Center (KDC) en MIT Kerberos 5 (también conocido como krb5) v1.8.x anterior a v1.8.4 no maneja correctamente un índice en una lista de autorizaciones de datos, lo cual permite a atacantes remotos provocar una denegación de servicio (caída del servicio), o posiblemente obtener información sensible, falsificación de autorización, o ejecutar código arbitrario mediante una solicitud TGS, como lo demuestra una petición de un cliente de Windows Active Directory.
