Debian DLA-3681-1 : amanda - LTS security update

high Nessus Plugin ID 186524

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3681 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)

- 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 (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

Upgrade the amanda packages.

For Debian 10 buster, these problems have been fixed in version 1
