Kerberos is a network authentication system, which can improve the security of your network by eliminating the insecure practice of sending passwords over the network in unencrypted form. It allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos key distribution center (KDC).

This update fixes the following bug:

* An earlier update to Kerberos, which was meant to proof the application for the "Year 2038 problem", introduced a bug in time stamp management. Consequently, Java and other programs did not behave as expected when requesting Kerberos tickets with lifetimes of maximum length. With this update, all requests for Kerberos tickets have a lifetime limit to avoid overflow. As a result, the requested lifetime is preserved, and the issuing of tickets by Kerberos now works correctly again. (BZ#1554723)

Users of krb5 are advised to upgrade to these updated packages, which fix this bug.
