3. Problem description:
The lm_sensors package includes a collection of modules for general SMBus
access and hardware monitoring. This package requires special support which
is not in standard version 2.2 kernels.
A bug was found in the way the pwmconfig tool creates temporary files. It
is possible that a local attacker could leverage this flaw to overwrite
arbitrary files located on the system. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2005-2672 to this issue.
Users of lm_sensors are advised to upgrade to these updated packages, which
contain a backported patch that resolves this issue.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
