Detects memory errors like buffer overflows and use-after-free bugs during C/C++ fuzzing and security audits.
AddressSanitizer (ASan) is a specialized memory error detection tool that instruments C, C++, and Rust code at compile time to identify critical vulnerabilities such as memory leaks, use-after-free, and buffer overflows. By utilizing shadow memory to track allocation states, it provides developers and security researchers with detailed crash reports and stack traces, making it an essential component for vulnerability discovery and software hardening during the testing and fuzzing phases.
