The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the ALINUX3-SA-2024:0001 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-2977:
    A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15     cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context.
    The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is     wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In     cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is     possible.

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-2024:0030 advisory.

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

    CVE-2021-34193:
    Stack overflow vulnerability in OpenSC smart card middleware before 0.23 via crafted responses to APDUs.

    CVE-2023-2977:
    A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15     cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context.
    The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is     wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In     cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is     possible.

    CVE-2023-40660:
    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-2023-4535:
    An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling     symmetric key encryption. Exploiting this flaw requires an attacker to have physical access to the     computer and a specially crafted USB device or smart card. This flaw allows the attacker to manipulate     APDU responses and potentially gain unauthorized access to sensitive data, compromising the system's     security.
