Subject: [USN-172-1] lm-sensors vulnerability

===========================================================
Ubuntu Security Notice USN-172-1	    August 23, 2005
lm-sensors vulnerabilities
https://bugzilla.ubuntu.com/show_bug.cgi?id=13887
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

lm-sensors

The problem can be corrected by upgrading the affected package to
version 2.8.8-7ubuntu2.1.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Javier Fernández-Sanguino Peña noticed that the pwmconfig script
created temporary files in an insecure manner. This could allow
a symlink attack to create or overwrite arbitrary files with full
root privileges since pwmconfig is usually executed by root.
