Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of babel installed on the remote host is prior to 0.9.6-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2010 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

Run 'yum update babel' to update your system.
