Test ID:1.3.6.1.4.1.25623.1.0.69197
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0923
Summary:NOSUMMARY
Description:Description:
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.

Solution:
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
