Title:RedHat Security Advisory RHSA-2010:0923
The remote host is missing updates announced in
advisory RHSA-2010:0923.

The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows
individual devices on an IP network to get their own network configuration
information, including an IP address, a subnet mask, and a broadcast
address. DHCPv6 is the DHCP protocol version for IPv6 networks.

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)

Users running dhcpd as a DHCPv6 server should upgrade to these updated
packages, which contain a backported patch to correct this issue. After
installing this update, all DHCP servers will be restarted automatically.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
