The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-4641 advisory.

  - Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and     IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application     is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this     attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12;
    v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.
    (CVE-2020-14422)

  - In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an     infinite loop when opened by tarfile.open, because _proc_pax lacks header validation. (CVE-2019-20907)

  - Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1     allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client     because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking. (CVE-2020-8492)

  - PyYAML 5.1 through 5.1.2 has insufficient restrictions on the load and load_all functions because of a     class deserialization issue, e.g., Popen is a class in the subprocess module. NOTE: this issue exists     because of an incomplete fix for CVE-2017-18342. (CVE-2019-20477)

  - A vulnerability was discovered in the PyYAML library in versions before 5.3.1, where it is susceptible to     arbitrary code execution when it processes untrusted YAML files through the full_load method or with the     FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this     flaw. An attacker could use this flaw to execute arbitrary code on the system by abusing the     python/object/new constructor. (CVE-2020-1747)

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