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