zzuf is a fuzzer software used for transparent application input. It is designed to identify faults in software by injecting unexpected inputs from various sources. It can be used to test network protocols, file formats, and daemons.
One key feature of zzuf is its deterministic behavior, which makes it easier to reproduce bugs. The primary areas of use for zzuf are quality assurance and security. Users can use zzuf to test existing software or integrate it into their own software's testsuite. In terms of security, zzuf is often successful in exposing potential security holes, such as segmentation faults or memory corruption issues.
Media players, image viewers, and web browsers are the primary targets for zzuf. These applications process inherently insecure data, making them ideal candidates for testing with zzuf. Interestingly, the software has also been successful in uncovering bugs in system utilities like objdump.
Overall, I found zzuf to be an innovative and helpful tool for testing and ensuring quality in software development. Additionally, the recent release includes bug fixes, including a crash with library initialization functions that use realloc() before the libc is ready.
