Recursion causes stack overflow which aborts process #121
Description
Trying to parse the following pdf contained within the zip file will cause a stack overflow.
The fuzzing harness I used to find this was modified from the existing one, since there's already lots of panics and I wanted to look for more interesting bugs.
#![no_main]
use libfuzzer_sys::fuzz_target;
fuzz_target!(|data: &[u8]| {
std::panic::set_hook(Box::new(|_| {}));
std::panic::catch_unwind(|| {
if let Ok(p) = pdf::file::File::from_data(data) {
for _ in p.pages() {}
}
});
});
