CVE-2022-37705: Zmanda Amanda

Medium severity, CVSS 6.7. EPSS: 1.3% chance of exploitation in the next 30 days.

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),
