NVD Description

Note: Versions mentioned in the description apply only to the upstream python27:2.7/python2-virtualenv package and not the python27:2.7/python2-virtualenv package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The pip package before 19.2 for Python allows Directory Traversal when a URL is given in an install command, because a Content-Disposition header can have ../ in a filename, as demonstrated by overwriting the /root/.ssh/authorized_keys file. This occurs in _download_http_url in _internal/download.py.
