Descriptions

The process_as_req function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x before 1.10.3 does not initialize a certain structure member, which allows remote attackers to cause a denial of service (uninitialized pointer dereference and daemon crash) or possibly execute arbitrary code via a malformed AS-REQ request.

La función process_as_req en Key Distribution Center (KDC) en MIT Kerberos 5 (también conocido como krb5) v1.10.x anteriores a v1.10.3 no inicializa ciertos miembros de la estructura de forma adecuada, lo que permite a atacantes remotos provocar una denegación de servicio (desreferencia a puntero no inicializado y caída del demonio)o posiblemente ejecutar código a través de una petición AS-REQ manipulada.

Multiple vulnerabilities have been discovered in MIT Kerberos 5, allowing execution of arbitrary code or Denial of Service. Versions less than 1.11.4 are affected.
