pkg-bugs Ubuntu has issued an advisory for this on May 27: https://ubuntu.com/security/notices/USN-4969-1 Fedora has issued an advisory for this on June 2: https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/Z2LB42JWIV4M4WDNXX5VGIP26FEYWKIF/ Advisory: ======================== Updated dhcp packages fix security vulnerability: A flaw was found in the Dynamic Host Configuration Protocol (DHCP). There is a discrepancy between the code that handles encapsulated option information in leases transmitted "on the wire" and the code which reads and parses lease information after it has been written to disk storage. This flaw allows an attacker to deliberately cause a situation where dhcpd while running in DHCPv4 or DHCPv6 mode, or the dhclient attempts to read a stored lease that contains option information, to trigger a stack-based buffer overflow in the option parsing code for colon-separated hex digits values. The highest threat from this vulnerability is to data confidentiality and integrity as well as service availability (CVE-2021-25217).

Fixed upstream in 4.4.2-P1 =>
(none) in the previous version, there was a bug with the notify to systemd; which meant that the service seemed to work at first and then stop with timeout after 1.5min. This version actually solves my issue... CC:
