Synopsis ========
lm_sensors is vulnerable to linking attacks, potentially allowing a local user to overwrite arbitrary files.
Background ==========
lm_sensors is a software package that provides drivers for monitoring the temperatures, voltages, and fans of Linux systems with hardware monitoring devices.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/lm_sensors < 2.9.1-r1 >= 2.9.1-r1
Description ===========
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.
Resolution ==========
All lm_sensors users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/lm_sensors-2.9.1-r1"
References ==========
