+# base-builder
+> Abstract base image for project builders.
+
+Every project image supports multiple commands that can be invoked through docker after the image is built:
+
+
+docker run --rm -ti gcr.io/oss-fuzz/$project <command> <arguments...>
+
+
+# Supported Commands
+
+| Command | Description |
+|---------|-------------|
+| `compile` (default) | build all fuzz targets
+| `/bin/bash` | drop into shell, execute `compile` script to start build.
+
+# Build Configuration
+
+A single build image can build same set of fuzzers in many configurations.
+The configuration is picked through one or more environment variables.
+
+| Env Variable | Description
+| ------------- | --------
+| `$SANITIZER ("address")` | Specifies predefined sanitizer configuration to use. `address` or `memory` or `undefined`.
+| `$SANITIZER_FLAGS` | Specify compiler sanitizer flags directly. Overrides `$SANITIZER`.
+| `$COVERAGE_FLAGS` | Specify compiler flags to use for fuzzer feedback coverage.
+| `$BUILD_UID` | User id to use while building fuzzers.
+
+## Examples
+
+- *building sqlite3 fuzzer with UBSan (`SANITIZER=undefined`):*
+
+
+
+docker run --rm -ti -e SANITIZER=undefined gcr.io/oss-fuzz/sqlite3
+
+
+
+# Image Files Layout
+
+| Location|Env| Description |
+|---------| -------- | ---------- |
+| `/out/` | `$OUT` | Directory to store build artifacts (fuzz targets, dictionaries, options files, seed corpus archives). |
+| `/src/` | `$SRC` | Directory to checkout source files |
+| `/work/`| `$WORK` | Directory for storing intermediate files |
+| `/usr/lib/libFuzzingEngine.a` | `$LIB_FUZZING_ENGINE` | Location of prebuilt fuzzing engine library (e.g. libFuzzer) that needs to be linked with all fuzz targets.
+
+While files layout is fixed within a container, the environment variables are
+provided to be able to write retargetable scripts.
+
+
+## Compiler Flags
+
+You *must* use special compiler flags to build your project and fuzz targets.
+These flags are provided in following environment variables:
+
+| Env Variable | Description
+| ------------- | --------
+| `$CC` | The C compiler binary.
+| `$CXX`, `$CCC` | The C++ compiler binary.
+| `$CFLAGS` | C compiler flags.
+| `$CXXFLAGS` | C++ compiler flags.
+
+Most well-crafted build scripts will automatically use these variables. If not,
+pass them manually to the build tool.

+# Child Image Interface
+
+## Sources
+
+Child image has to checkout all sources that it needs to compile fuzz targets into
+`$SRC` directory. When the image is executed, a directory could be mounted on top
+of these with local checkouts using
+`docker run -v $HOME/my_project:/src/my_project ...`.
+
+## Other Required Files
+
+Following files have to be added by child images:
+
+| File Location | Description |
+| ------------- | ----------- |
+| `$SRC/build.sh` | build script to build the project and its fuzz targets |

+# System Sanitizers
+
+We use `ptrace` to instrument system calls made by the target program to detect
+various vulnerabilities.
+
+## Command injection
+
+This detector currently works by
+
+- Checking if `execve` is called with `/tmp/tripwire` (which comes from our dictionary).
+- Checking if `execve` is invoking a shell with invalid syntax. This is likely
+ caused by our input.
+
+## Arbitrary file open
+
+TODO: documentation.
+
+## Proof of concept
+
+### Cleanup
+Note this will delete /tmp/tripwire if it exists.
+```shell
+make clean
+```
+
+### Run test
+Note this will overwrite /tmp/tripwire if it exists.
+```shell
+make test
+```
+
+Look for one of the following lines:
+
+> ===BUG DETECTED: Shell injection===
+
+which indicates the detection of executing the planted `/tmp/tripwire`.
+
+
+> ===BUG DETECTED: Shell corruption===
+
+which indicates the detection of executing a syntactic erroneous command.
+
+
+### Command injection PoC in Python with `pytorch-lightning`
+With `SystemSan`, [`Artheris`](https://github.com/google/atheris) can detect a shell injection bug in [version v1.5.10 of `pytorch-lightning`](https://github.com/PyTorchLightning/pytorch-lightning/tree/1.5.0).
+```shell
+make pytorch-lightning-1.5.10
+```
+
+### Command injection PoC in JavaScript with `shell-quote`
+With `SystemSan`, [`Jsfuzz`](https://gitlab.com/gitlab-org/security-products/analyzers/fuzzers/jsfuzz) can detect a shell corrpution bug in [the latest version (v1.7.3) of `shell-quote`](https://github.com/substack/node-shell-quote) without any seed.
+```shell
+make node-shell-quote-v1.7.3
+```
+This is based on [a shell injection exploit report](https://wh0.github.io/2021/10/28/shell-quote-rce-exploiting.html) of [version v1.7.2 of `shell-quote`](https://github.com/substack/node-shell-quote/tree/v1.7.2).
+`SystemSan` can also discover the same shell injection bug with a corpus file containing:
+```
+`:`/tmp/tripwire``:`
+```
