Debian DLA-2790-1 : python-babel - LTS security update

high Nessus Plugin ID 154330

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2790 advisory.

Tenable discovered that in Babel, a set of tools for internationalizing Python applications, Babel.Locale allows attackers to load arbitrary locale .dat files (containing serialized Python objects) via directory traversal, leading to code execution. This vulnerability was also previously addressed under CVE-2021-20095 in other distributions and suites. For Debian 9 stretch, this problem has been fixed in version 2.3.4+dfsg.1-2+deb9u1. We recommend that you upgrade your python-babel packages. For the detailed security status of python-babel please refer to its security tracker page at: https://security- tracker.debian.org/tracker/python-babel Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at:
https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the python-babel packages.

For Debian 9 stretch, this problem has been fixed in version 2.3.4+dfsg.1-2+deb9u1.
