Title:RHSA-2018:0158: dhcp security update (Moderate)
Description: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. The dhcp packages provide a relay agent and ISC DHCP service required to enable and administer DHCP on a network.

Security Fix(es):

  • It was found that the DHCP daemon did not properly clean up closed OMAPI connections in certain cases. A remote attacker able to connect to the OMAPI port could use this flaw to exhaust file descriptors in the DHCP daemon, leading to a denial of service in the OMAPI functionality. (CVE-2017-3144)
