"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the TSSA-2024:0921 advisory.

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

    CVE-2024-5629:
    An out-of-bounds read in the 'bson' module of PyMongo 4.6.2 or earlier allows deserialization of malformed
    BSON provided by a Server to raise an exception which may contain arbitrary application memory.

    CVE-2024-21506:
    Versions of the package pymongo before 4.6.3 are vulnerable to Out-of-bounds Read in the bson module.
    Using the crafted payload the attacker could force the parser to deserialize unmanaged memory. The parser
    tries to interpret bytes next to buffer and throws an exception with string. If the following bytes are
    not printable UTF-8 the parser throws an exception with a single byte.

Tenable has extracted the preceding description block directly from the Tencent 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.");
