Synopsis
========
lm_sensors is vulnerable to a symlink attack, potentially allowing a
local user to overwrite arbitrary files.

Background
==========
lm_sensors provides essential tools for monitoring the hardware health
of Linux systems containing hardware health monitoring hardware such as
the LM78 and LM75

Description
===========
CAN-2005-2672:
pwmconfig in LM_sensors before 2.9.1 creates temporary files insecurely,
which allows local users to overwrite arbitrary files via a symlink
attack on the fancontrol temporary file.

Affected packages
=================
lm_sensors in all grimoires is affected. This is now fixed in devel,
test, stable-rc 0.2 and stable 0.1 grimoires.

Resolution
==========
All lm_sensors users should upgrade to the latest available version:
         # scribe update
         # cast -c lm_sensors
