Red Hat Security Advisory: java-1.8.0-openjdk security update
The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit. 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. (RHEL-102903) 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.

Technical Summary
The Red Hat Security Advisory RHSA-2025:10861 updates the java-1.8.0-openjdk packages to address four security vulnerabilities identified as CVE-2025-30749, CVE-2025-30754, CVE-2025-30761, and CVE-2025-50106. These issues involve improvements to glyph drawing, TLS protocol support, and scripting capabilities within the JDK. The update also fixes a bug where java.net.InetAddress.getLocalHost().getHostName() returned a fully qualified hostname instead of the short hostname on IPv4-preferred systems, aligning behavior across interfaces. The advisory is rated as important by Red Hat Product Security and targets Red Hat Enterprise Linux Server 7 Extended Lifecycle Support variants. No CVSS base scores are provided, and no known exploits in the wild are reported.
Potential Impact
The vulnerabilities fixed by this update affect the OpenJDK 8 runtime and development environment on Red Hat Enterprise Linux 7 Extended Lifecycle Support. The issues relate to graphical rendering (glyph drawing), TLS protocol handling, and scripting support, which could potentially impact application security and stability. The hostname resolution bug fix improves consistency in network behavior. Red Hat rates the security impact as important, indicating a significant but not critical risk. There are no reports of active exploitation in the wild at this time.
Mitigation Recommendations
Red Hat has released an official security update for java-1.8.0-openjdk packages on Red Hat Enterprise Linux 7 Extended Lifecycle Support. Users should apply this update promptly to remediate the identified vulnerabilities and bug. Before applying, ensure all previously released errata relevant to the system are installed. Detailed update instructions are available from Red Hat's official documentation. No alternative mitigations are indicated or required beyond applying the provided update.
