A vulnerability was found in GNU Nano that allows a possible privilege
escalation through an insecure temporary file. If Nano is killed while
editing, a file it saves to an emergency file with the permissions of the
running user provides a window of opportunity for attackers to escalate
privileges through a malicious symlink.
