The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-2764 advisory.

  - An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path     when processing some 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; in such a scenario, they could trigger     excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
    For example, the attack payload could be placed in the Location header of an HTTP response with status     code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. (CVE-2022-45061)

  - 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-2020-10735)

  - Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection     against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is     disputed by a third party because the http.server.html documentation page states Warning: http.server is     not recommended for production. It only implements basic security checks. (CVE-2021-28861)

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