# LibAFL with launcher for libpng with qemu arm32 in usermode
|
|
|
|
This folder contains an example fuzzer for libpng using the qemu emulator in arm32 usermode.
|
|
To show off crash detection, we added an optional undefined instruction to the harness.
|
|
Everything has been tested on Linux.
|
|
|
|
In contrast to the normal libfuzzer libpng example, this uses the `launcher` feature, that automatically spawns `n` child processes, and binds them to a free core.

|
|
## Prerequisites
|
|
```bash
|
|
sudo apt install gcc-arm-linux-gnueabi g++-arm-linux-gnueabi
|
|
```
|
|
|
|
## Run
|
|
|
|
```bash
|
|
cargo make run
|
|
```
|

## Run with artifical crash
|
