    Summary: Updated gnutls packages fix security vulnerability

    Details: Updated gnutls packages fix security vulnerability: It was found that GnuTLS 3.6.4 introduced a regression in the TLS protocol implementation. This caused the TLS server to not securely construct a session ticket encryption key considering the application supplied secret, allowing a MitM attacker to bypass authentication in TLS 1.3 and recover previous conversations in TLS 1.2 (CVE-2020-13777).
