Michal Jaegermann has reported a security issue in Fedora, which can be exploited by malicious, local users to perform certain actions with escalated privileges.
The security issue is caused due to the buttonpressed.sh script from the scanbuttond package using temporary files in an insecure manner. This can be exploited via symlink attacks to overwrite or delete arbitrary files with root privileges.
The security issue is reported in scanbuttond-0.2.3-10.fc7. Other versions may also be affected.
Solution: Restrict access to trusted users only.
