Description David Walser 2013-04-17 20:35:34 CEST

RedHat has issued an advisory on April 16:
https://rhn.redhat.com/errata/RHSA-2013-0748.html

Cauldron is not affected (bug eliminated through code refactoring in 1.11).

Patched package uploaded for Mageia 2.

Patch checked into Mageia 1 SVN.

Advisory:
========================

Updated krb5 packages fix security vulnerability:

A NULL pointer dereference flaw was found in the way the MIT Kerberos KDC
processed certain TGS (Ticket-granting Server) requests. A remote,
authenticated attacker could use this flaw to crash the KDC via a
specially-crafted TGS request (CVE-2013-1416).

Testing complete on Mageia 2 i586 using the procedure from

Testing complete on Mageia 2 x86_64.

Could someone from the sysadmin team push the srpm
krb5-1.9.2-2.5.mga2.src.rpm
from Mageia 2 Core Updates Testing to Core Updates.
