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

  - In Python 3 through 3.9.0, the
    Lib/test/multibytecodec_support.py CJK codec tests call
    eval() on content retrieved via HTTP.(CVE-2020-27619)

  - http.client in Python 3.x before 3.5.10, 3.6.x before
    3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5
    allows CRLF injection if the attacker controls the HTTP
    request method, as demonstrated by inserting CR and LF
    control characters in the first argument of
    HTTPConnection.request.(CVE-2020-26116)

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.");
