Red Hat Security Advisory: OpenJDK 21.0.2 security update

Notes

Topic
An update is now available for OpenJDK. 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.
Details
The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software Development Kit. This release of the Red Hat build of OpenJDK 21 (21.0.2) for portable Linux serves as a replacement for the Red Hat build of OpenJDK 21 (21.0.1) and includes security and bug fixes, and enhancements. For further information, refer to the release notes linked to in the References section. Security Fix(es): * OpenJDK: array out-of-bounds access due to missing range check in C1 compiler (8314468) (CVE-2024-20918) * OpenJDK: RSA padding issue and timing side-channel attack against TLS (8317547) (CVE-2024-20952) * OpenJDK: JVM class file verifier flaw allows unverified bytecode execution (8314295) (CVE-2024-20919) * OpenJDK: range check loop optimization issue (8314307) (CVE-2024-20921) * OpenJDK: logging of digital signature private keys (8316976) (CVE-2024-20945) 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.
