Summary
Important: java-17-openjdk security update
Details

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

Security Fix(es):

  • JDK: Improve JMX connections (CVE-2026-21925)
  • JDK: Improve HttpServer Request handling (CVE-2026-21933)
  • JDK: Enhance Certificate Checking (CVE-2026-21945)
  • libpng: LIBPNG buffer overflow (CVE-2025-64720)
  • libpng: LIBPNG heap buffer overflow (CVE-2025-65018)

Bug Fix(es):

  • When using a P11SecretKey for both signing and encryption in FIPS mode, the FIPS PKCS11 provider would fail with a CKR_ATTRIBUTE_VALUE_INVALID error. This was due to the default configuration not applying the CKA_ENCRYPT=true attribute to the key. The configuration in this release is updated to include this attribute. (AlmaLinux-142862, AlmaLinux-142881, AlmaLinux-142882, AlmaLinux-142883, AlmaLinux-142884, AlmaLinux-142885, AlmaLinux-142886, AlmaLinux-142887, AlmaLinux-142888)
