"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0894 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-8443:
    A heap-based buffer overflow vulnerability was found in the libopensc OpenPGP driver. A crafted USB device
    or smart card with malicious responses to the APDUs during the card enrollment process using the
    `pkcs15-init` tool may lead to out-of-bound rights, possibly resulting in arbitrary code execution.

    CVE-2024-45620:
    A vulnerability was found in the pkcs15-init tool in OpenSC. An attacker could use a crafted USB Device or
    Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are
    partially filled with data, initialized parts of the buffer can be incorrectly accessed.

    CVE-2024-45619:
    A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker could
    use a crafted USB Device or Smart Card, which would present the system with a specially crafted response
    to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly
    accessed.

    CVE-2024-45618:
    A vulnerability was found in pkcs15-init in OpenSC. An attacker could use a crafted USB Device or Smart
    Card, which would present the system with a specially crafted response to APDUs.

    Insufficient or missing checking of return values of functions leads to unexpected work with variables
    that have not been initialized.

    CVE-2024-45617:
    A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker could
    use a crafted USB Device or Smart Card, which would present the system with a specially crafted response
    to APDUs.

    Insufficient or missing checking of return values of functions leads to unexpected work with variables
    that have not been initialized.

    CVE-2024-45616:
    A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker could
    use a crafted USB Device or Smart Card, which would present the system with a specially crafted response
    to APDUs.

    The following problems were caused by insufficient control of the response APDU buffer and its length when
    communicating with the card.

    CVE-2024-45615:
    A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK.
    The problem is missing  initialization of variables expected to be initialized (as arguments to other
    functions, etc.).
