high Nessus Plugin ID 51824

Language:

Synopsis

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

Description

ISC reports :

When the DHCPv6 server code processes a message for an address that was previously declined and internally tagged as abandoned it can trigger an assert failure resulting in the server crashing. This could be used to crash DHCPv6 servers remotely. This issue only affects DHCPv6 servers. DHCPv4 servers are unaffected.

Solution

Update the affected package.
