Beyond Spatial and Temporal Memory Safety

The unsafe features of C often lead to memory errors that can result in vulnerabilities. Dynamic analysis tools are widely used to detect such errors at runtime and enforce memory safety. It is widely believed that memory safety exactly consists of spatial and temporal safety, thus all existing analysis tools aim at detecting spatial or temporal errors. In this paper, we introduce another class of memory safety, namely segment safety, which has been neglected in previous work. Indeed, state-of-the-art analysis tools cannot detect segment errors. Thus we propose and implement a new approach to detect segment errors at runtime.
