    Summary: Moderate: dhcp security and bug fix update

    Details: 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.

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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
