Synopsis:	Moderate: dhcp security update
Issue date:	2010-11-30
CVE Names:	CVE-2010-3611

A NULL pointer dereference flaw was discovered in the way the dhcpd
daemon parsed DHCPv6 packets. A remote attacker could use this flaw to
crash dhcpd via a specially-crafted DHCPv6 packet, if dhcpd was running
as a DHCPv6 server. (CVE-2010-3611)

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