patches/packages/gnutls-3.6.14-x86_64-1_slack14.2.txz
Fixed insecure session ticket key construction, since 3.6.4. The TLS server
would not bind the session ticket encryption key with a value supplied by
the application until the initial key rotation, allowing attacker to bypass
authentication in TLS 1.3 and recover previous conversations in TLS 1.2.
