-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Important: gnutls and nettle security update Advisory ID: RHSA-2021:1246-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:1246 Issue date: 2021-04-19 CVE Names: CVE-2021-20305 ===================================================================== 1. Summary: An update for gnutls and nettle is now available for Red Hat Enterprise Linux 8.2 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux AppStream EUS (v. 8.2) - aarch64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux BaseOS EUS (v. 8.2) - aarch64, ppc64le, s390x, x86_64 3. 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. Security Fix(es): * nettle: Out of bounds memory access in signature verification (CVE-2021-20305) 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. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5.
