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

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"
