Description

Javier Fernandez-Sanguino Pena noticed that the pwmconfig script created temporary files in an insecure manner. This could allow a symlink attack to create or overwrite arbitrary files with full root privileges since pwmconfig is usually executed by root.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
