And that will continue to be the case.

Rather, fix your scripts to sanitize the input before they even get
anywhere near your config file ACLs (the chance of PANIC case slipping
in there an taking your whole config down is rather a large DOS
loop whole).

Remember the contents of ACLs are meant to be maintained by a person
who can guarantee the sanity of them, not for them to be opened up
to arbitrary chunks of data/user input.
