high Nessus Plugin ID 154330

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 a vulnerability as referenced in the dla-2790 advisory.

- Babel.Locale in Babel before 2.9.1 allows attackers to load arbitrary locale .dat files (containing serialized Python objects) via directory traversal, leading to code execution. (CVE-2021-42771)

Note that Nessus has not tested for this issue 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.
