A vulnerability has been identified in Fedora, which could be exploited by local attackers to bypass security restrictions. This issue is caused by an error in the "/etc/scanbuttond/buttonpressed.sh" script that insecurely uses certain temporary files, which could allow malicious users to conduct symlink attacks and overwrite arbitrary files with the privileges of the user invoking the vulnerable script.
