|Title:||RedHat Update for dhcp RHSA-2011:0256-01|
|Summary:||The remote host is missing an update for the 'dhcp'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'dhcp'
package(s) announced via the referenced advisory.
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 flaw was found in the way the dhcpd daemon processed certain DHCPv6
messages for addresses that had previously been declined and marked as
abandoned internally. If a remote attacker sent such messages to dhcpd, it
could cause dhcpd to crash due to an assertion failure if it was running as
a DHCPv6 server. (CVE-2011-0413)
Red Hat would like to thank Internet Systems Consortium for reporting this
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.
