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.
