CVE-2011-4868 low priority: Debian including 1 source packages (isc-dhcp), 4 status rows across 4 suites (bookworm, bullseye, sid, trixie): resolved 4.
The logging functionality in dhcpd in ISC DHCP before 4.2.3-P2, when using Dynamic DNS (DDNS) and issuing IPv6 addresses, does not properly handle the DHCPv6 lease structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets related to a lease-status update.
