Synopsis
========

Multiple vulnerabilities have been found in BusyBox, allowing context
dependent attackers to load arbitrary kernel modules, execute arbitrary
files, or cause a Denial of Service condition.

Background
==========

BusyBox is set of tools for embedded systems and is a replacement for
GNU Coreutils.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  sys-apps/busybox             < 1.23.1                  >= 1.23.1 

Description
===========

Multiple vulnerabilities have been discovered in BusyBox.  Please
review the CVE identifiers referenced below for details.

Impact
======

A context-dependent attacker can load kernel modules without privileges
by nullifying enforced module
prefixes. Execution of arbitrary files or a Denial of Service can be
caused through the included vulnerable LZO library.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All BusyBox users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-apps/busybox-1.23.1"
