Explore a 14-minute conference talk from USENIX OSDI '21 that introduces SANRAZOR, an innovative tool designed to reduce redundant sanitizer checks in C/C++ programs. Learn about the challenges of high runtime costs associated with sanitizers and how SANRAZOR's hybrid approach, combining dynamic code coverage and static data dependencies, effectively detects and removes unnecessary checks. Discover the significant performance improvements achieved by SANRAZOR, reducing AddressSanitizer overhead from 73.8% to 28.0–62.0% and UndefinedBehaviorSanitizer overhead from 160.1% to 36.6–124.4%. Gain insights into the tool's effectiveness in detecting vulnerabilities and its potential for synergistic integration with existing sanitizer reduction tools, ultimately enhancing the efficiency of software debugging and vulnerability discovery processes.
