Description

 Usermin contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when the /tmp/.webmin directory has been created prior to installation. It is possible for a malicious user to create a symlink to any other file on the system, which would be overwritten when Usermin writes to the link filename, resulting in a loss of integrity.
