Overview

Affected versions of this package are vulnerable to Arbitrary Code Execution by crafting a Firejail container that is accepted by the Firejail setuid-root program as a join target. A local attacker can enter an environment in which the Linux user namespace is still the initial user namespace, the NO_NEW_PRIVS protocol is not activated, and the entered mount namespace is under the attacker's control.
