Hi,
The following vulnerability was published for gnutls28.
CVE-2020-24659[0]:
| An issue was discovered in GnuTLS before 3.6.15. A server can trigger
| a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation
| alert is sent with unexpected timing, and then an invalid second
| handshake occurs. The crash happens in the application's error
| handling path, where the gnutls_deinit function is called after
| detecting a handshake failure.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
