issues in the COS kernel.

c. ESX third party update for Service Console krb5 RPM
This patch updates the krb5-libs and krb5-workstation RPMs to
version 1.6.1-63.el5_7 to resolve a security issue.
By default, the affected krb5-telnet and ekrb5-telnet services
do not run. The krb5 telnet daemon is an xinetd service. You
can run the following commands to check if krb5 telnetd is
enabled:
/sbin/chkconfig --list krb5-telnet
/sbin/chkconfig --list ekrb5-telnet
The output of these commands displays if krb5 telnet is enabled.
You can run the following commands to disable krb5 telnet
daemon:
/sbin/chkconfig krb5-telnet off
/sbin/chkconfig ekrb5-telnet off
