medium Nessus Plugin ID 57550

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

ISC reports :

Due to improper handling of a DHCPv6 lease structure, ISC DHCP servers that are serving IPv6 address pools AND using Dynamic DNS can encounter a segmentation fault error while updating lease status under certain conditions.

The potential exists for this condition to be intentionally triggered, resulting in effective denial of service to clients expecting service from the affected server.

Solution

Update the affected package.
