A flaw was found in samba’s DNS server. An authenticated user could use
this flaw to the RPC server to crash. This RPC server, which also serves
protocols other than dnsserver, will be restarted after a short delay, but
it is easy for an authenticated non administrative attacker to crash it
again as soon as it returns. The Samba DNS server itself will continue to
operate, but many RPC services will not.
