漏洞信息
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.
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 (denial of service). (CVE-2016-2774)
