CWE-284  (opens in a new tab)

How to fix?

Upgrade netblue30/firejail to version 0.9.38.12, 0.9.44.8 or higher.

Overview

Affected versions of this package are vulnerable to Improper Access Control. Firejail before 0.9.44.6 and 0.9.38.x LTS before 0.9.38.10 LTS does not comprehensively address dotfile cases during its attempt to prevent accessing user files with an euid of zero, which allows local users to conduct sandbox-escape attacks via vectors involving a symlink and the --private option. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-5180.
