gnutls28 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.10


GnuTLS could expose sensitive information over the network.

performing DTLS negotiation. A remote attacker could possibly use this
issue to obtain sensitive information, contrary to expectations.

package versions:

Ubuntu 19.10:
