FreeBSD : Weechat -- Possible man-in-the-middle attack in TLS connection to servers (3ba1ca94-a563-11ec-8be6-d4c9ef517024)

high Nessus Plugin ID 158995

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 3ba1ca94-a563-11ec-8be6-d4c9ef517024 advisory.

 - The Weechat project reports: After changing the options weechat.network.gnutls_ca_system or weechat.network.gnutls_ca_user, the TLS verification function is lost. Consequently, any connection to a server with TLS is made without verifying the certificate, which could lead to a man-in-the-middle attack. Connection to IRC servers with TLS is affected, as well as any connection a server made by a plugin or a script using the function hook_connect.
 (3ba1ca94-a563-11ec-8be6-d4c9ef517024)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
