Description Laura Pardo 2018-02-16 19:27:58 UTC 
A NULL pointer dereference was found in Irssi in complete_from_nicklist function
of chat-completion.c file, when an "empty" nick joins a channel. A remote
attacker, who can control an IRC server, could crash IRC clients by leveraging
this vulnerability.
