| Description: | The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS.
Nettle is a cryptographic library that is designed to fit easily in almost any context: In crypto toolkits for object-oriented languages, such as C++, Python, or Pike, in applications like LSH or GNUPG, or even in kernel space.
The following packages have been upgraded to a later upstream version: gnutls (3.6.16). (BZ#1956783)
Security Fix(es):
nettle: Remote crash in RSA decryption via manipulated ciphertext (CVE-2021-3580)
gnutls: Use after free in client key_share extension (CVE-2021-20231)
gnutls: Use after free in client_send_params in lib/ext/pre_shared_key.c (CVE-2021-20232)
