JD has discovered a security issue in WeeChat, which can be exploited by malicious people to conduct spoofing attacks.
The security issue is caused due to the application not verifying the validity of the SSL certificates presented when logging in to a server which does not request a client certificate during the handshake. This can be exploited to spoof a valid server and e.g. conduct Man-in-the-Middle (MitM) attacks.
The security issue is confirmed in version 0.3.4. Other versions may also be affected.
Solution: Update to version 0.3.5 or later.
