Title:	CentOS Update for dhclient CESA-2012:1141 centos6
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. A denial of service flaw was found in the way the dhcpd daemon handled zero-length client identifiers. A remote attacker could use this flaw to send a specially-crafted request to dhcpd, possibly causing it to enter an infinite loop and consume an excessive amount of CPU time. (CVE-2012-3571) Two memory leak flaws were found in the dhcpd daemon. A remote attacker could use these flaws to cause dhcpd to exhaust all available memory by sending a large number of DHCP requests. (CVE-2012-3954) Upstream acknowledges Markus Hietava of the Codenomicon CROSS project as the original reporter of CVE-2012-3571, and Glen Eustace of Massey University, New Zealand, as the original reporter of CVE-2012-3954. Users of DHCP should upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, all DHCP servers will be restarted automatically. Affected Software/OS: dhclient on CentOS 6 Solution: Please install the updated packages. CVSS Score: 6.1 CVSS Vector: AV:A/AC:L/Au:N/C:N/I:N/A:C
