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

Critical Nessus Plugin ID 14155


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


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.


Update the affected packages.
