3. Description:

Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third- party, the Key Distribution Center (KDC).

A buffer overflow flaw was found in the MIT krb5 telnet daemon
(telnetd). A remote attacker who can access the telnet port of a
target machine could use this flaw to execute arbitrary code as
root. (CVE-2011-4862)

Note that the krb5 telnet daemon is not enabled by default in any
version of Red Hat Enterprise Linux. In addition, the default firewall
rules block remote access to the telnet port. This flaw does not
affect the telnet daemon distributed in the telnet-server package.

For users who have installed the krb5-workstation package, have
enabled the telnet daemon, and have it accessible remotely, this
update should be applied immediately.

All krb5-workstation users should upgrade to these updated packages,
which contain a backported patch to correct this issue.

4. Solution:

The krb5 telnet daemon is an xinetd service. You can determine if krb5
telnetd is enabled with the commands:

/sbin/chkconfig --list krb5-telnet 
/sbin/chkconfig --list ekrb5-telnet 

The output of these commands will display "on" if krb5 telnet is
enabled.  krb5 telnet daemon can be immediately disabled with the
commands:

/sbin/chkconfig krb5-telnet off
/sbin/chkconfig ekrb5-telnet off

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):
