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].
