"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2026:42876 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: Enhance TLS certificate handling (CVE-2026-46968)

    * JDK: Enhance JPEG handling (CVE-2026-47010)

    * JDK: Enhance XBM image support (CVE-2026-47021)

    * JDK: Enhance Jar file processing (CVE-2026-47027)

    * JDK: Improve certification checking (CVE-2026-60147)

    * JDK: Enhance AWT ImagingLib (CVE-2026-47059)

    * JDK: Enhance Jar handling (CVE-2026-47063)

    * JDK: Improve Nashorn index handling (CVE-2026-47057)

    * JDK: Enhance Dataview Implementation (CVE-2026-47058)

    * JDK: Update LCMS to 2.19 (CVE-2026-41254)

    Enhancements:

    * For the last couple of years, OpenJDK has used a single build shared among multiple RPMs and a tarball
    available on the customer portal.  The single portable build has a release number ('p') and each RPM has
    its own release number ('r').  However, the RPM naming only showed the RPM release number, while the
    version output from the build showed the portable release number, making it unclear that they were
    different numbers.  From this release onwards, a release field of the form 'p.r' is always used for RPMs
    and the version output shows 'p'. (RHEL-212138)

    Bug Fix(es):

    * In previous releases, the RPM did not correctly own the subdirectories used for documentation in
    /usr/share/doc and /usr/share/javadoc.  This is fixed in this release, so these subdirectories will be
    removed when the package is uninstalled. (RHEL-212148)

    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.");
