"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3668 advisory.

  - A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated
    by one process, it can perform cryptographic operations in other processes when an empty zero-length pin
    is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small,
    permanently connected tokens to computers. Additionally, the token can internally track login status. This
    flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system
    without the user's awareness. (CVE-2023-40660)

  - Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card
    enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of
    these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB
    device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise
    key generation, certificate loading, and other card management operations during enrollment.
    (CVE-2023-40661)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
