Synopsis

Important: OpenJDK 8u462 Security Update for Portable Linux Builds

Type/Severity

Security Advisory: Important

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.

Description

The OpenJDK 8 packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit.

This release of the Red Hat build of OpenJDK 8 (8u462) for portable Linux serves as a replacement for Red Hat build of OpenJDK 8 (8u452) and includes security and bug fixes as well as enhancements. For further information, refer to the release notes linked to in the References section.

Security Fix(es):

  • JDK: Better Glyph drawing (CVE-2025-30749)
  • JDK: Enhance TLS protocol support (CVE-2025-30754)
  • JDK: Improve scripting supports (CVE-2025-30761)
  • JDK: Better Glyph drawing redux (CVE-2025-50106)

Bug Fix(es):

  • On certain system configurations where the IPv4 stack was preferred over IPv6 (either due to -Djava.net.preferIPv4Stack=true being specified or no IPv6 interfaces being present), the method java.net.InetAddress.getLocalHost().getHostName() would return the fully qualified hostname instead of the short hostname. This behavior was only ever intended for Solaris systems and it deviated from the method's behavior for IPv6 interfaces. In this release, the method will return the short hostname on all interfaces. (OPENJDK-3966)
