"According to the versions of the python3 packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - Lib/zipfile.py in Python through 3.7.2 allows remote
    attackers to cause a denial of service (resource
    consumption) via a ZIP bomb.(CVE-2019-9674)

  - In Python (CPython) 3.6 through 3.6.10, 3.7 through
    3.7.6, and 3.8 through 3.8.1, an insecure dependency
    load upon launch on Windows 7 may result in an
    attacker's copy of api-ms-win-core-path-l1-1-0.dll
    being loaded and used instead of the system's copy.
    Windows 8 and later are unaffected.(CVE-2020-8315)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
