A SUID program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces and seccomp-bpf.
Multiple vulnerabilities have been discovered in Firejail. Please review upstream’s release notes below for details.
A remote attacker could possibly bypass sandbox protection, cause a Denial of Service condition, or change a system’s DNS server.
There is no known workaround at this time.
All Firejail users should switch to the newly added LTS version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/firejail-lts-0.9.38.6"
Users who want to stay on the current branch should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/firejail-0.9.44.2"
