Pipenv check thinks pip is ancient, fails citing CVE-2013-5123

I’ve searched through existing issues, and tried to find clues in the source (which I’ve never cracked open before). Neither turned up anything for me, so here’s an issue!

Issue description

pipenv check fails when checking pip version. It warns about an issue in version of pip older than 1.5. I’ve seen this on a macOS machine and a circleci docker image running pip 19.3.1 and 20.0.3 respectively.

I’m using Python 3.6, and managing python versions with pyenv.

Expected result

Since the installed version of pip is greater than 1.5, I would expect this check to pass instead of fail.

Actual result

Checking installed package safety…
37752: pip  resolved (19.3.1 installed)!
The mirroring support (-M, --use-mirrors) in Python Pip before 1.5 uses insecure DNS querying and authenticity checks which allows attackers to perform man-in-the-middle attacks. See CVE-2013-5123.

Steps to replicate

Here’s a handy little script to reproduce.

mkdir pipenv_check
cd pipenv_check
pipenv --python 3.6
pipenv check

The fix in pyupio/safety-db#2286 should be enough to resolve this issue. I verified pipenv check is no longer complaining on my projects. Closing this issue. Thanks @thehesiod for your help!
