MTSan - A Feasible and Practical Memory Sanitizer for Fuzzing COTS Binaries

Explore a groundbreaking presentation from USENIX Security '23 on MTSan, a novel hardware-assisted memory sanitizer designed for binary fuzzing. Discover how this innovative tool addresses the challenges of detecting memory safety violations in commercial off-the-shelf (COTS) binaries without access to source code. Learn about MTSan's progressive object recovery scheme, customized binary rewriting solution, and utilization of ARM Memory Tagging Extension (MTE) to enhance effectiveness while reducing runtime overhead. Gain insights into the implementation and evaluation of MTSan on AArch64, and understand its potential to revolutionize vulnerability detection in binary fuzzing compared to existing sanitizers.
