Synopsis:	Moderate: dhcp security update
Issue date:	2011-02-15
CVE Names:	CVE-2011-0413

A flaw was found in the way the dhcpd daemon processed certain DHCPv6
messages for addresses that had previously been declined and marked as
abandoned internally. If a remote attacker sent such messages to dhcpd, 
it could cause dhcpd to crash due to an assertion failure if it was 
running as a DHCPv6 server. (CVE-2011-0413)

After installing this update, all DHCP servers will be restarted 
automatically.

SL 6.x
