Fedora 34 Critical: GnuTLS 3.7.1 TLS Enhancements and Security Fixes

GnuTLS is a secure communications library implementing the SSL, TLS and DTLS

protocols and technologies around them. It provides a simple C language

application programming interface (API) to access the secure communications

protocols as well as APIs to parse and write X.509, PKCS #12, OpenPGP and

other required structures.

and CVE-2021-20232, fipscheck build-dep removal, and TLS 1.3 middlebox

compatibility mode fixes. ---- Fix cert chain verification if it contains

duplicate certs.
