FKIE_CVE-2011-4868

Vulnerability from fkie_nvd - Published: 2012-01-15 03:55 - Updated: 2025-04-11 00:51
Severity ?
Summary
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.
