Bug Fix Advisory - RHBA-2014:0494-1
------------------------------------------------------------------------------
Summary:
krb5 bug fix update

Updated krb5 packages that fix one bug are now available for Red Hat Enterprise Linux 5.


Description:
Kerberos is an authentication system which allows clients and services to authenticate to each other with the help of a trusted third party, a Kerberos KDC.

This update fixes the following bug:

* Previously, when the krb5 client library was waiting for a response from a server, the timeout variable in certain cases became a negative number.
Consequently, the client could enter a loop while checking for responses. With this update, the client logic has been modified and the described error no longer occurs. (BZ#1095364)
