openSUSE 15 Security Update : amanda (openSUSE-SU-2023:0069-1)

medium Nessus Plugin ID 172560

Language:

Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2023:0069-1 advisory.

 - A privilege escalation flaw was found in Amanda 3.5.1 in which the backup user can acquire root privileges. The vulnerable component is the runtar SUID program, which is a wrapper to run /usr/bin/tar with specific arguments that are controllable by the attacker. This program mishandles the arguments passed to tar binary (it expects that the argument name and value are separated with a space; however, separating them with an equals sign is also supported), (CVE-2022-37705)

 - Amanda 3.5.1 allows privilege escalation from the regular user backup to root. The SUID binary located at /lib/amanda/rundump will execute /usr/sbin/dump as root with controlled arguments from the attacker which may lead to escalation of privileges, denial of service, and information disclosure. (CVE-2022-37704)

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

Solution

Update the affected amanda package.
