Summary
Moderate: gnutls and nettle security, bug fix, and enhancement update
Details

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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
