Red Hat Security Advisory

Synopsis:           Important: java-17-openjdk security and bug fix update  
Advisory ID:        RHSA-2024:0267-03  
Product:            Red Hat Enterprise Linux  
Advisory URL:       https://access.redhat.com/errata/RHSA-2024:0267  
Issue date:         2024-01-17  
Revision:           03  
CVE Names:          CVE-2024-20918  
====================================================================

Summary: 

An update for java-17-openjdk is now available for Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 8.8 Extended Update Support, Red Hat Enterprise Linux 9, and Red Hat Enterprise Linux 9.2 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.

Description:

The java-17-openjdk packages provide the OpenJDK 17 Java Runtime Environment and the OpenJDK 17 Java Software Development Kit.

Security Fix(es):

* OpenJDK: array out-of-bounds access due to missing range check in C1 compiler (8314468) (CVE-2024-20918)

* OpenJDK: incorrect handling of ZIP files with duplicate entries (8276123) (CVE-2024-20932)

* 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.

Bug Fix(es):

* When Transparent Huge Pages (THP) are unconditionally enabled on a system, Java applications using many threads were found to have a large Resident Set Size (RSS). This was due to a race between the kernel transforming thread stack memory into huge pages and the Java Virtual Machine (JVM) shattering these pages into smaller ones when adding a guard page. This release resolves this issue by getting glibc to insert a guard page and prevent the creation of huge pages. (RHEL-13930, RHEL-13931, RHEL-13934, RHEL-13935)
