Abstract

Most malicious attacks compromise system security through memory corruption exploits. Recently proposed techniques attempt to defeat these attacks by protecting program control data. We have constructed a new class of attacks that can compromise network applications without tampering with any control data. These non-control data attacks represent a new challenge to system security. In this paper, we propose an architectural technique to defeat both control data and non-control data attacks based on the notion of pointer taintedness. A pointer is said to be tainted if user input can be used as the pointer value. A security attack is detected whenever a tainted value is dereferenced during program execution. The proposed architecture is implemented on the SimpleScalar processor simulator and is evaluated using synthetic programs as well as real-world network applications. Our technique can effectively detect both control data and non-control data attacks, and it offers better security coverage than current methods. The proposed architecture is transparent to existing programs.
