If this generates taint errors, I'm surprised that exiftool doesn't
generate more.  The value of $format is obtained from an unpack('S',...)
call, so the result is guaranteed to be either undefined or a number
in the range 0 to 65535.  How is this a security problem when used
in a sprintf format string?
