Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. Also note that this plugin does not distinguish between Python packages installed via the OS package manager, Python packages installed via PIP, or other sources. As a result, packages provided by your OS package repository may have backported fixes that this plugin may incorrectly report as vulnerable.
