Firejail before 0.9.44.4 and 0.9.38.x LTS before 0.9.38.8 LTS does not consider the .Xauthority case 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.

Security readout for executives and security teams

CVE-2017-5180 is a local sandbox-escape issue in Firejail. Older Firejail versions mishandled a .Xauthority edge case while trying to block root-effective access to user files. A local user could use the --private option and a symlink-related vector to escape intended isolation. Exposure is most likely on Linux systems that installed Firejail versions older than 0.9.44.4, or the 0.9.38.x LTS branch before 0.9.38.8 LTS. Risk is higher where Firejail is treated as a strong security boundary for local users or desktop workloads. Treat this as a targeted remediation item for systems using Firejail, not a broad internet-facing emergency. Prioritize hosts where local users, shared workstations, or desktop applications depend on Firejail for containment. Mitigation focus: Upgrade Firejail to 0.9.44.4 or later where applicable.; For 0.9.38.x LTS, upgrade to 0.9.38.8 LTS or later.; Check distribution advisories, including Gentoo GLSA-201701-62, for packaged fixes..
