What is it ?
|
||||
------
|
||||
|
||||
This directory contains fuzz targets.
|
||||
Fuzz targets are simple codes using the library.
|
||||
They are used with a so-called fuzz driver, which will generate inputs, try to process them with the fuzz target, and alert in case of an unwanted behavior (such as a buffer overflow for instance).
|
||||
|
||||
These targets were meant to be used with oss-fuzz but can be used in other contexts.
|
||||
|
||||
This code was contributed by Philippe Antoine ( Catena cyber ).
|
||||
|
||||
How to run ?
|
||||
------
|
||||
|
||||
To run the fuzz targets like oss-fuzz :
|
||||
```
|
||||
git clone https://github.com/google/oss-fuzz
|
||||
cd oss-fuzz
|
||||
python infra/helper.py build_image mbedtls
|
||||
python infra/helper.py build_fuzzers --sanitizer address mbedtls
|
||||
python infra/helper.py run_fuzzer mbedtls fuzz_client
|
||||
```
|
||||
You can use `undefined` sanitizer as well as `address` sanitizer
|
||||
And you can run any of the fuzz targets like `fuzz_client`
|
||||
|
||||
To run the fuzz targets without oss-fuzz, you first need to install one libFuzzingEngine (libFuzzer for instance)
|
||||
Then you need to compile the code
|
||||
```
|
||||
perl scripts/config.pl set MBEDTLS_PLATFORM_TIME_ALT
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
```
|
||||
Finally, you can run the targets like `./test/fuzz/fuzz_client`
