Description

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.

Description

The unaffected packages listed in GLSA 201612-48 had an incomplete fix as reported by Sebastian Krahmer of SuSE. This has been properly patched in the latest releases.

Impact

An attacker could possibly bypass sandbox protection, cause a Denial of Service condition, or escalate privileges.

Workaround

There is no known workaround at this time.

Resolution

All Firejail users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=sys-apps/firejail-0.9.44.8"

All Firejail-lts users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=sys-apps/firejail-lts-0.9.38.10"
