The java-11-openjdk packages provide the OpenJDK 11 Java Runtime Environment and the OpenJDK 11 Java Software Development Kit.

Security Fix(es):

• OpenJDK: certificate path validation issue during client authentication (8309966) (CVE-2023-22081)

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):

• Additional validity checks in the handling of Zip64 files, JDK-8302483, were introduced in the 11.0.20 release of OpenJDK, causing the use of some valid zip files to now fail with an error. This release, 11.0.20.1, allows for zero-length headers and additional padding produced by some Zip64 creation tools. With both releases, the checks can be disabled using -Djdk.util.zip.disableZip64ExtraFieldValidation=true. (RHBZ#2237170)

• A maximum signature file size property, jdk.jar.maxSignatureFileSize, was introduced in the 11.0.20 release of OpenJDK by JDK-8300596, with a default of 8 MB. This default proved to be too small for some JAR files. This release, 11.0.20.1, increases it to 16 MB.

• The serviceability agent would print an exception when encountering null addresses while producing thread dumps. These null values are now handled appropriately. (JDK-8243210, RHEL-2763)

• The /usr/bin/jfr alternative is now owned by the java-11-openjdk package (RHEL-13559)

• The jcmd tool is now provided by the java-11-openjdk-headless package, rather than java-11-openjdk-devel, to make it more accessible (RHEL-13566)
