Mandrake Linux Security Advisory : krb5 (MDKSA-2004:056-1)

This script is Copyright (C) 2004-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandrake Linux host is missing one or more security
updates.

Description :

Multiple buffer overflows exist in the krb5_aname_to_localname()
library function that if exploited could lead to unauthorized root
privileges. In order to exploit this flaw, an attacker must first
successfully authenticate to a vulnerable service, which must be
configured to enable the explicit mapping or rules-based mapping
functionality of krb5_aname_to_localname, which is not a default
configuration.

Mandrakesoft encourages all users to upgrade to these patched krb5
packages.

Update :

The original patch provided contained a bug where rule-based entries
on systems without HAVE_REGCOMP would not work. These updated packages
provide the second patch provided by Kerberos development team which
fixes that behaviour.
