Synopsis
========
Firejail is vulnerable to the escalation of privileges due to an
incomplete fix for CVE-2017-5180.
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 < 0.9.44.8 >= 0.9.44.8
2 sys-apps/firejail-lts < 0.9.38.10 >= 0.9.38.10
——————————————————————-
2 affected packages
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 -v “>=sys-apps/firejail-lts-0.9.38.10”
