The remote Redhat Enterprise Linux 10 / 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:42895 advisory.

    The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software     Development Kit.

    Security Fix(es):

    * JDK: Enhance TLS certificate handling (CVE-2026-46968)

    * JDK: Improve DTLS handshaking (CVE-2026-46917)

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

    Enhancement(s):

    * 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-212337, RHEL-212338, RHEL-212339, RHEL-212340, RHEL-212342,     RHEL-212343)

    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-212353, RHEL-212359, RHEL-212360, RHEL-212361)

    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.
