Description Malte Kraus 2019-08-23 15:09:49 UTC 
> An issue was discovered in LINBIT csync2 through 2.0.
> The client and daemon do not correctly check for
> the return value GNUTLS_E_WARNING_ALERT_RECEIVED of gnutls_handshake().
> They neglect to call the function multiple times in order to retrieve
> all return values, potentially allowing remote attackers to create TLS
> connections with unhandled validation or connection issues.
>
