GLSA 201702-03: Firejail: Privilege escalation

http://security.gentoo.org/

Severity:	high
Title:	Firejail: Privilege escalation
Date:	02/09/2017
Bugs:	#607382
ID:	201702-03

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	Architecture(s)
sys-apps/firejail	< 0.9.44.8	>= 0.9.44.8	All supported architectures
sys-apps/firejail-lts	< 0.9.38.10	>= 0.9.38.10	All supported architectures

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"
