QID 353121: Amazon Linux Security Advisory for python-pip : ALAS2-2022-1742

A flaw was found in python-urllib3.
Ssl certificate validation is omitted in some cases involving https to https proxies.
The initial connection to the https proxy (if an sslcontext isn't given via proxy_config) doesn't verify the hostname of the certificate.
This means certificates for different servers that still validate properly with the default urllib3 sslcontext will be silently accepted. (
