Ervin Nemeth has reported a vulnerability in mirrorselect, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.
The vulnerability is caused due to temporary files being created insecurely. This can be exploited via symlink attacks to overwrite arbitrary files on the system with the privileges of the user executing the mirrorselect tool.
