Synopsis

The remote RockyLinux host is missing one or more security updates.

Description

The remote RockyLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:0928 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. (Rocky Linux-142860, Rocky Linux-142876, Rocky Linux-142877, Rocky Linux-142878, Rocky Linux-142879, Rocky Linux-142880)
