Description Nalin Dahyabhai 2004-06-01 21:27:54 UTC
Description of problem:

The krb5_aname_to_localname() library function contains multiple
buffer overflows which could be exploited to gain unauthorized root
access.

Only configurations which include auth_to_local_names or auth_to_local
directives (neither of which are included in default configurations)
are vulnerable.

Comment 1 Seth Vidal 2004-06-04 19:38:20 UTC
the errata that were just issued for this for fc1 and fc2, did they
apply the first patch or the second from the mit announcement.

they issued a correction to the patch and I wanted to make sure the
bug was not present.
