RHSA-2016:2590-02 -- Redhat dhcp

ID: oval:org.secpod.oval:def:501921Date: (C)2016-11-07   (M)2023-12-20
Class: PATCHFamily: unix




The Dynamic Host Configuration Protocol 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. The dhcp packages provide a relay agent and ISC DHCP service required to enable and administer DHCP on a network. Security Fix: * A resource-consumption flaw was discovered in the DHCP server. dhcpd did not restrict the number of open connections to OMAPI and failover ports. A remote attacker able to establish TCP connections to one of these ports could use this flaw to cause dhcpd to exit unexpectedly, stop responding requests, or exhaust system sockets . Red Hat would like to thank ISC for reporting this issue. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.
