Patch  oval:com.redhat.rhsa:def:20100923
RHSA-2010:0923: dhcp security update (Moderate)  

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.

Quick Help

Unknown Tests
There is a hardcoded maximum limit for number of tests displayed for a definition. For a small number of oval definitions, about ~1% of all, hundreds of test have been defined. This causes the pages to grow in size, exceed even 1mb, and they are unsuitable for display in a web page. So they are not displayed.Please refer to the xml definition files if you really want to view them.
evr_string datatype
Represents epoch, version, and release number as a single version string
