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
