Another similar overflow panic issue is about json::parse(). If I pass a very long str, it may crash due to overflow. I put the replay file at https://github.com/StevenJiang1110/afl_rust_crashes/tree/main/json/replay_json53-1. I think it's better to restrict the input string len. The above is found by afl.rs. Thanks a lot.
If we provide a capacity too large, the program may crash. The code to replay the crash is as below.
I run the code on my x86-64 machine, ubuntu18.04, and the error report is
I think it's better to restrict the capacity and return a Result instead of letting it crash alone, especially on x64 machine, where the length of usize is 64bits. The above is found by afl.rs. Thanks a lot.
