 Description
 -----------

  kerberos5:
  * The krb5_aname_to_localname() library function contains multiple
    buffer overflows which could be exploited to gain unauthorized root
    access.  Exploitation of these flaws requires an unusual combination
    of factors, including successful authentication to a vulnerable
    service and a non-default configuration on the target service. This
    flaw effects all releases of MIT Kerberos 5 [0], up to and including
    krb5-1.3.3.

    This problem has been assigned the id MITKRB5-SA-2004-001 [1].
