lm_sensors is a software package that provides drivers for
|
|
monitoring the temperatures, voltages, and fans of Linux systems with
|
|
hardware monitoring devices.

<description>

<p>
|
|
Javier Fernandez-Sanguino Pena has discovered that lm_sensors
|
|
insecurely creates temporary files with predictable filenames when
|
|
saving configurations.
|
|

<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary file
|
|
directory, pointing to a valid file somewhere on the filesystem. When
|
|
the pwmconfig script of lm_sensors is executed, this would result in
|
|
the file being overwritten with the rights of the user running the
|
|
script, which typically is the root user.
|

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

All lm_sensors users should upgrade to the latest version:

<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/lm_sensors-2.9.1-r1"</code>
