Computer Science originator contributor text Technical reports New York Department of Computer Science, Columbia University 2011 Just as errors in sequential programs can lead to security exploits, errors in concurrent programs can lead to concurrency attacks. In this paper, we present an in-depth study of concurrency attacks and how they may affect existing defenses. Our study yields several interesting findings. For instance, we find that concurrency attacks can corrupt non-pointer data, such as user identifiers, which existing memory-safety defenses cannot handle. Inspired by our findings, we propose new defense directions and fixes to existing defenses.
