The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Several buffer overflows when handling responses from an ePass 2003 Card in decrypt_response in     libopensc/card-epass2003.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted     smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
    (CVE-2018-16420)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2019:2154 advisory.

    The OpenSC set of libraries and utilities provides support for working with smart cards. OpenSC focuses on     cards that support cryptographic operations and enables their use for authentication, mail encryption, or     digital signatures.
