CVE-2011-4868
Last modified
CVE-2011-4868 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.61% chance of exploitation in the next 30 days.
