Red Hat Product Errata RHSA-2011:0200 0 normal SHIPPED_LIVE Important: krb5 security update 2011-02-08 21:51:54 UTC

Description Jan Lieskovsky 2010-12-17 18:11:33 UTC 
A denial of service flaw was found in the way kpropd,
a Kerberos V5 slave KDC update server, processed certain
update requests for KDC database propagation. A remote,
unauthenticated user could use this flaw to cause kpropd
daemon to terminate (stop the Kerberos server replication
process).
Comment 1 Jan Lieskovsky 2010-12-17 18:14:04 UTC 
This issue did NOT affect the versions of the krb5 package,
