"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2024:1608 advisory.

    The opencryptoki packages contain version 2.11 of the PKCS#11 API, implemented for IBM Cryptocards, such
    as IBM 4764 and 4765 crypto cards. These packages includes support for the IBM 4758 Cryptographic
    CoProcessor (with the PKCS#11 firmware loaded), the IBM eServer Cryptographic Accelerator (FC 4960 on IBM
    eServer System p), the IBM Crypto Express2 (FC 0863 or FC 0870 on IBM System z), and the IBM CP Assist for
    Cryptographic Function (FC 3863 on IBM System z). The opencryptoki packages also bring a software token
    implementation that can be used without any cryptographic hardware. These packages contain the Slot Daemon
    (pkcsslotd) and general utilities.

    Security Fix(es):

    * opencryptoki: timing side-channel in handling of RSA PKCS#1 v1.5 padded ciphertexts (Marvin)
    (CVE-2024-0914)

    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.");
