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

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

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

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'

Risk factor :

Low / CVSS Base Score : 2.1
