This research aims to develop a technique that prevents buffer overflow vulnerabilities and memory errors in software applications.
Implemented a compiler that inserts dynamic checks into generated code.
Collected and tested widely used open source servers including Apache and Sendmail.
Inserted checks detect out of bounds memory accesses and utilize a hash table for error handling.
The compiler successfully allows servers to process requests even during buffer overflow attempts.
All tested open source servers were shown to be free from buffer overflow vulnerabilities using the new technique.

No takes yet. Share an insight, caveat, or question.

Randomized trial demonstrates improved security against buffer overflow in servers, suggesting a novel programming approach.

Rinard et al. (2005) studied this question.
