HylaFAX+ through 7.0.2 has scripts that execute binaries from directories
writable by unprivileged users (e.g., locations under /var/spool/hylafax that
are writable by the uucp account). This allows these users to execute code in
the context of the user calling these binaries (often root) (CVE-2020-15397).
