RHSA-2023:0946 — Security Advisory

An update for openssl is now available for Red Hat Enterprise Linux 9.

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.

[Updated 20 March 2023] Previously, this erratum was marked as having a security impact of Moderate. This was incorrect; the security impact of this erratum has been changed to Important, to correctly reflect the highest impact rating of CVE fixes included in this release. No changes have been made to packages.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es):
