RHEL 8 / 9 : java-1.8.0-openjdk (RHSA-2026:0932)

high Nessus Plugin ID 296625

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for java-1.8.0-openjdk.

Description

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:0932 advisory.

 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: 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. (RHEL-142865, RHEL-142866, RHEL-142867, RHEL-142868, RHEL-142869, RHEL-142870, RHEL-142871, RHEL-142872, RHEL-142873, RHEL-142874)

 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL java-1.8.0-openjdk package based on the guidance in RHSA-2026:0932.
