SCA: security update for PyInstaller (GHSA-7fcj-pq9j-wh2r)

high Tenable Self-Hosted Container Security Plugin ID 422681

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In PyInstaller before version 3.6, only on Windows, a local privilege escalation vulnerability is present
 in this particular case: If a software using PyInstaller in "onefile" mode is launched by a privileged
 user (at least more than the current one) which have his "TempPath" resolving to a world writable
 directory. This is the case for example if the software is launched as a service or as a scheduled task
 using a system account (TempPath will be C:\Windows\Temp). In order to be exploitable the software has to
 be (re)started after the attacker launch the exploit program, so for a service launched at startup, a
 service restart is needed (e.g. after a crash or an upgrade). (CVE-2019-16784)
