GLSA-200508-19 : lm_sensors: Insecure temporary file creation

low Nessus Plugin ID 19572

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200508-19 (lm_sensors: Insecure temporary file creation)

Javier Fernandez-Sanguino Pena has discovered that lm_sensors insecurely creates temporary files with predictable filenames when saving configurations.
Impact :

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 :

There is no known workaround at this time.

Solution

All lm_sensors users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/lm_sensors-2.9.1-r1'
