## Description

WeeChat (aka Wee Enhanced Environment for Chat) 3.2 to 3.4 before 3.4.1
does not properly verify the TLS certificate of the server, after certain
GnuTLS options are changed, which allows man-in-the-middle attackers to
spoof a TLS chat server via an arbitrary certificate. NOTE: this only
affects situations where weechat.network.gnutls\_ca\_system or
weechat.network.gnutls\_ca\_user is changed without a WeeChat restart.
