AlmaLinux 9 : java-17-openjdk (ALSA-2026:0927)
high Nessus Plugin ID 296490
Synopsis
The remote AlmaLinux host is missing one or more security updates.Description
The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2026:0927 advisory.* 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)
