Título:	RedHat Security Advisory RHSA-2012:1141
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2012:1141. 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. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2012-1141.html http://www.isc.org/software/dhcp/advisories/cve-2012-3571 http://www.isc.org/software/dhcp/advisories/cve-2012-3954 Risk factor : Medium
