Published Jul 26, 2026 · Updated Jul 26, 2026

Ecosystem: Rocky Linux

Summary

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

Security Fix(es):

* JDK: Enhance TLS certificate handling (CVE-2026-46968)

* JDK: Improve DTLS handshaking (CVE-2026-46917)

* JDK: Enhance JPEG handling (CVE-2026-47010)

* JDK: Enhance XBM image support (CVE-2026-47021)

* JDK: Improve certification checking (CVE-2026-60147)

* JDK: Enhance AWT ImagingLib (CVE-2026-47059)

* JDK: Enhance Jar handling (CVE-2026-47063)

* JDK: Update LCMS to 2.19 (CVE-2026-41254)

Enhancement(s):

* For the last couple of years, OpenJDK has used a single build shared among multiple RPMs and a tarball available on the customer portal. The single "portable" build has a release number ('p') and each RPM has its own release number ('r'). However, the RPM naming only showed the RPM release number, while the version output from the build showed the portable release number, making it unclear that they were different numbers. From this release onwards, a release field of the form 'p.r' is always used for RPMs and the version output shows 'p'. (Rocky Linux-212474, Rocky Linux-212475, Rocky Linux-212476, Rocky Linux-212477, Rocky Linux-212478, Rocky Linux-212479, Rocky Linux-212480, Rocky Linux-212481)
