Firejail Symlink Sandbox-Escape Vulnerability

CVE-2017-5180 · MEDIUM Severity

AV:L/AC:L/AU:N/C:P/I:P/A:P

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.
