Description Martin Prpič 2015-04-08 08:19:08 UTC

The following issue was found in node:

The SIGQUIT routine fails to close the app leaving the IP sockets open and in some cases DDOS the remote site if a user "ctrl-]+q" out of a telnet session. Also the app fails to close and more can be spawned by a crafty malicious user thus bringing the system to a point of no memory available.
