Image-rs/image

This crate provides basic image processing functions and methods for converting to and from various image formats.

Build Docker

$ sudo docker build -t oss-sydr-fuzz-image-rs .

Run Hybrid Fuzzing

Unzip Sydr (sydr.zip) in projects/image-rs directory:

$ unzip sydr.zip

Run docker:

$ sudo docker run --cap-add=SYS_PTRACE  --security-opt seccomp=unconfined -v /etc/localtime:/etc/localtime:ro --rm -it -v $PWD:/fuzz oss-sydr-fuzz-image-rs /bin/bash

Prepare Initial Corpus

You could find initial seeds in image repo and copy them to /fuzz/corpus directory. Example for tiff parser:

# mkdir /fuzz/corpus && find /image -name "*.tiff" -exec cp {} /fuzz/corpus \;

Run Fuzzing

Change directory to /fuzz:

# cd /fuzz

Run hybrid fuzzing:

# sydr-fuzz -c tiff.toml run

Collect coverage:

# sydr-fuzz -c tiff.toml cov-export -- -format=lcov > tiff.lcov
# genhtml --ignore-errors source -o tiff_html tiff.lcov
