webmin -- insecure temporary file creation at installation time


The Webmin developers documented a security issue in the release notes for version 1.160:

Fixed a security hole in the script, used to create the /tmp/.webmin directory at install time. If an un-trusted user creates this directory before Webmin is installed, he could create in it a symbolic link pointing to a critical file on the system, which would be overwritten when Webmin writes to the link filename.
