Descriptions

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.

WeeChat (también se conoce como Wee Enhanced Environment for Chat) versiones 3.2 a 3.4 anteriores a 3.4.1 no verifica correctamente el certificado TLS del servidor, después de que sean cambiadas determinadas opciones de GnuTLS, lo que permite a atacantes d tipo man-in-the-middle falsificar un servidor de chat TLS por medio de un certificado arbitrario. NOTA: esto sólo afecta a las situaciones en las que weechat.network.gnutls_ca_system o weechat.network.gnutls_ca_user son cambiadas sin reiniciar WeeChat
