Synopsis

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

Description

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-e295804b3d advisory.

 - In Amanda 3.5.1, an information leak vulnerability was found in the calcsize SUID binary. An attacker can abuse this vulnerability to know if a directory exists or not anywhere in the fs. The binary will use `opendir()` as root directly without checking the path, letting the attacker provide an arbitrary path.
 (CVE-2022-37703)

 - 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)

 - 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)

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.
