"The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2896
advisory.

  - IPython (Interactive Python) is a command shell for interactive computing in multiple programming
    languages, originally developed for the Python programming language. Affected versions are subject to an
    arbitrary code execution vulnerability achieved by not properly managing cross user temporary files. This
    vulnerability allows one user to run code as another on the same machine. All users are advised to
    upgrade. (CVE-2022-21699)

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