Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-4539 low priority: Debian including 1 source packages (isc-dhcp), 4 status rows across 4 suites (bookworm, bullseye, sid, trixie): resolved 4.
dhcpd in ISC DHCP 4.x before 4.2.3-P1 and 4.1-ESV before 4.1-ESV-R4 does not properly handle regular expressions in dhcpd.conf, which allows remote attackers to cause a denial of service (daemon crash) via a crafted request packet.
