Vulnerability Assessment Details

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

Vulnerability Assessment Summary
lm_sensors: Insecure temporary file creation

Detailed Explanation for this Vulnerability Assessment
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.

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