3. Description:

pip is a package management system used to install and manage software
packages written in Python. Many packages can be found in the Python
Package Index (PyPI). pip is a recursive acronym that can stand for either
"Pip Installs Packages" or "Pip Installs Python". 

Security Fix(es):

* python-urllib3: Cross-host redirect does not remove Authorization header
allow for credential exposure (CVE-2018-20060)

* python-urllib3: CRLF injection due to not encoding the '\r\n'
 sequence
leading to possible attack on internal service (CVE-2019-11236)

* python-urllib3: Certification mishandle when error should be thrown
(CVE-2019-11324)

* python-requests: Redirect from HTTPS to HTTP does not remove
Authorization header (CVE-2018-18074)
