We present Code Phage (CP), a system for automatically transferring correct code from donor applications into recipient applications that process the same inputs to successfully eliminate errors in the recipient. Experimental results using seven donor applications to eliminate ten errors in seven recipient applications highlight the ability of CP to(More)
We present Code Phage (CP), a system for automatically transferring correct code from donor applications into recipient applications to successfully eliminate errors in the recipient. Experimental results using six donor applications to eliminate nine errors in six recipient applications highlight the ability of CP to transfer code across applications to(More)
We present a new technique and system, DIODE, for auto- matically generating inputs that trigger overflows at memory allocation sites. DIODE is designed to identify relevant sanity checks that inputs must satisfy to trigger overflows at target memory allocation sites, then generate inputs that satisfy these sanity checks to successfully trigger the(More)
We present Targeted Automatic Patching (TAP), an automatic buffer and integer overflow discovery and patching system. Starting with an application and a seed input that the application processes correctly, TAP dynamically analyzes the execution of the application to locate target memory allocation sites and statements that access dynamically or statically(More)
