Description
In GNOME glib-networking through 2.64.2, the implementation of
GTlsClientConnection skips hostname verification of the server's TLS
certificate if the application fails to specify the expected server
identity. This is in contrast to its intended documented behavior, to
fail the certificate verification. Applications that fail to provide
the server identity, including Balsa before 2.5.11 and 2.6.x before
2.6.1, accept a TLS certificate if the certificate is valid for any
host.
Fixed in >= 2.64.3 https://gitlab.gnome.org/GNOME/glib-networking/-/commit/dbc8d69f58b07f6ed091aa123e5d40a53573a5fc
