I can’t say for sure, I cannot get it to pop that same error again. I will try opening it from another iPhone with lockdown enabled later.
I wouldn’t even know where to start in looking at that PDF for some sort of iOS exploit payload, my guess is it would be extremely difficult to find (if it exists).
