We detected that weechat is vulnerable to a crash when sending a special coloured message. This vulnerability hits versions old from one year ago to now.

Just update your clients! (or run /set irc.network.colors_receive off)

FYI. I won't have time to look into during this weekend, but someone
Superseded by ports/173514.
