Description
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-appl-servers package, have enabled
the krb5 telnet daemon, and have it accessible remotely, this update should
be applied immediately.
