Debian Security Advisory

DSA-814-1 lm-sensors -- insecure temporary file

Date Reported:
15 Sep 2005
Affected Packages:
lm-sensors
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 324193.
In Mitre's CVE dictionary: CVE-2005-2672.
More information:

Javier Fernández-Sanguino Peña discovered that a script of lm-sensors, utilities to read temperature/voltage/fan sensors, creates a temporary file with a predictable filename, leaving it vulnerable for a symlink attack.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 2.9.1-1sarge2.

For the unstable distribution (sid) this problem has been fixed in version 2.9.1-7.

We recommend that you upgrade your lm-sensors package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
