<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>It was discovered that there was a directory traversal attack in pip, the
Python package installer.</p>
<p>When an URL was given in an install command, as a
<tt>Content-Disposition</tt> header was permitted to have <tt>../</tt>
components in their filename, arbitrary local files (eg.
<tt>/root/.ssh/authorized_keys</tt>) could be overidden.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-20916">CVE-2019-20916</a>
<p>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.</p></li>
</ul>
<p>For Debian 9 <q>Stretch</q>, these problems have been fixed in version
9.0.1-2+deb9u2.</p>
<p>We recommend that you upgrade your python-pip packages.</p>

these updates to your system and frequently asked questions can be
