Description Martin Prpič 2015-05-22 07:41:58 UTC

A denial of service flaw was found in nbd:

"The listener/root server process terminates on SIGPIPE during negotiation. This is hardly the desired behavior, since any malfunctioning client can brought the listener server down by closing the socket unexpectedly."
