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

caused through the included vulnerable LZO library.

Workaround

Resolution
==========

All BusyBox users should upgrade to the latest version:

# emerge --sync
