NVD Description

Note: Versions mentioned in the description apply only to the upstream weechat package and not the weechat package as distributed by Alpine. See How to fix? for Alpine:3.15 relevant fixed versions and status.

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.
