Security issues fixed :

CVE-2019-18902: Fixed a use-after-free when receiving invalid DHCP6
client options (bsc#1160903).

CVE-2019-18903: Fixed a use-after-free when receiving invalid DHCP6
IA_PD option (bsc#1160904).

CVE-2020-7216: Fixed a potential denial of service via a memory leak
when processing packets with missing message type option in DHCP4
(bsc#1160905).

CVE-2020-7217: Fixed a memory leak in DHCP4 fsm when processing
packets for other client ids (bsc#1160906).

Non-security issue fixed :

dhcp4: Fixed an intermittent hang during network setup by cleaning up
the defer timer pointer (bsc#1142214).

Note that Tenable Network Security has extracted the preceding
