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,
as shipped with Red Hat Enterprise Linux 4 and 5.

This issue affects the version of the krb5 package,
