(RHSA-2023:2502) Moderate: dhcp security and enhancement update

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):

• dhcp: option refcount overflow when leasequery is enabled leading to dhcpd abort (CVE-2022-2928)

• dhcp: DHCP memory leak (CVE-2022-2929)
