CVE-2022-2929 is fixed in 12 products on 1 platform, first by isc-dhcp-client 4.3.5-3ubuntu7.4, released October 4, 2022. It is not reported as exploited. Patch Radar priority: Routine.
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) 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. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.8 Release Notes linked from the References section.
