Workaroundpython-twisted-web-0:12.1.0-7.el7_8.ppc64 as a component of Red Hat Enterprise Linux Server Optional (v. 7)redhat_csaf
When python-twisted-web is used as the back-end of your infrastructure, you can partially mitigate the problem by ensuring that each request on the front-end component (e.g. proxy) is sent over a separate network connection to the python-twisted-web server. This will prevent interference between different users, but it will not prevent all possible attacks that can be performed, which would vary based on the infrastructure and application in use.
