"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2025:0421 advisory.

    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 array handling (CVE-2025-21502)

    Bug Fix(es):

    * The Red Hat OpenJDK packages rely on the copy-jdk-configs package to transfer configuration files to a
    new updated JDK. The version of this package in RHEL 8.4 has been outdated for some time and contains bugs
    that have been fixed in later RHEL versions. With this update, both copy-jdk-configs and the JDK have been
    updated to use the latest version of copy-jdk-configs, which has been used for some years on later RHEL
    versions (RHEL-73870).

    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 this issue but has instead relied only on the application's self-reported version
number.");
