DHCPv6 is the DHCP protocol version for IPv6 networks.A NULL pointer dereference flaw was discovered in the way the dhcpd daemonparsed DHCPv6 packets. A remote attacker could use this flaw to crash dhcpdvia a specially-crafted DHCPv6 packet, if dhcpd was running as a DHCPv6server. (CVE-2010-3611)Users running dhcpd as a DHCPv6 server should upgrade to these updatedpackages, which contain a backported patch to correct this issue.
