    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).
