"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0112 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:
      CVE-2020-10735:
      A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when
    using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for
    1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not
    affected). The highest threat from this vulnerability is to system availability.
      CVE-2021-28861:
      A vulnerability was found in python. This security flaw causes an open redirection vulnerability in
    lib/http/server.py due to no protection against multiple (/) at the beginning of the URI path. This issue
    may lead to information disclosure.
      CVE-2022-45061:
      A vulnerability was discovered in Python. A quadratic algorithm exists when processing inputs to the
    IDNA (RFC 3490) decoder, such that a crafted unreasonably long name being presented to the decoder could
    lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled
    by a malicious actor, which could trigger excessive CPU consumption on the client attempting to make use
    of an attacker-supplied hostname.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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