Summary:	The remote host is missing an update for the 'dhclient'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'dhclient' package(s) announced via the referenced advisory. Vulnerability Insight: 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. Two denial of service flaws were found in the way the dhcpd daemon handled certain incomplete request packets. A remote attacker could use these flaws to crash dhcpd via a specially-crafted request. (CVE-2011-2748, CVE-2011-2749) Users of DHCP should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing this update, all DHCP servers will be restarted automatically. Affected Software/OS: dhclient on CentOS 5 Solution: Please install the updated packages. CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
