Amazon Linux 2 : amanda (ALAS-2023-2218)

high Nessus Plugin ID 180092

Language:

Synopsis

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

Description

The version of amanda installed on the remote host is prior to 3.3.9-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2218 advisory.

- An issue was discovered in Amanda 3.3.1. A user with backup privileges can trivially compromise a client installation. The runtar setuid root binary does not check for additional arguments supplied after
--create, allowing users to manipulate commands and perform command injection as root. (CVE-2016-10729)

- An issue was discovered in Amanda 3.3.1. A user with backup privileges can trivially compromise a client installation. Amstar is an Amanda Application API script. It should not be run by users directly. It uses star to backup and restore data. It runs binaries with root permissions when parsing the command line argument --star-path. (CVE-2016-10730)

- AMANDA (Advanced Maryland Automatic Network Disk Archiver) before tag-community-3.5.4 mishandles argument checking for runtar.c, a different vulnerability than CVE-2022-37705. (CVE-2023-30577)

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

Solution

Run 'yum update amanda' to update your system.
