Detail
| 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. |

| Id | Description |
|---|---|
| 18905 | lm_sensors /tmp/fancontrol Symlink Arbitrary File Overwrite lm_sensors contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered by the pwmconfig script, which creates the temporary file "/tmp/fancontrol" insecurely when saving the configuration. This can allow the user to creat or overwrite arbitrary files with the privileges of the user invoking the vulnerable script via a well timed symlink. This flaw may lead to a loss of availability and integrity. |
