Title:	RedHat Update for dhcp RHSA-2011:1819-01
Summary:	The remote host is missing an update for the 'dhcp'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'dhcp' 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 DHCP request packets when regular expression matching was used in '/etc/dhcp/dhcpd.conf'. A remote attacker could use this flaw to crash dhcpd. (CVE-2011-4539) Users of DHCP 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. Affected Software/OS: dhcp on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
