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
-------------------------------------------------------------------
1 sys-apps/firejail < 0.9.44.2 >= 0.9.44.2
2 sys-apps/firejail-lts >= 0.9.38.6
-------------------------------------------------------------------
2 affected packages

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"
