Package        : python-pip
Version        : 9.0.1-2+deb9u2
CVE ID         : CVE-2019-20916

It was discovered that there was a directory traversal attack in pip,
the Python package installer.

When an URL was given in an install command, as a Content-Disposition
header was permitted to have "../" components in their filename,
arbitrary local files (eg. /root/.ssh/authorized_keys) could be
overidden.

For Debian 9 "Stretch", this problem has been fixed in version
9.0.1-2+deb9u2.

We recommend that you upgrade your python-pip packages.

For the detailed security status of python-pip please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/python-pip
