Synopsis

Multiple vulnerabilities have been discovered in Firejail, the worst of which may allow bypassing of sandbox protection.

Background

A SUID program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces and seccomp-bpf.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
sys-apps/firejail	< 0.9.44.2	>= 0.9.44.2	All supported architectures
sys-apps/firejail-lts		>= 0.9.38.6	All supported architectures

Description

Multiple vulnerabilities have been discovered in Firejail. Please review upstream’s release notes below for details.

Impact

A remote attacker could possibly bypass sandbox protection, cause a Denial of Service condition, or change a system’s DNS server.

Workaround

There is no known workaround at this time.

Resolution

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"
