Abstract
A computer device includes a memory. The computer device also includes at least one processor configured to execute a process and manage the memory for the process. The processor is further configured to execute one or more program instructions associated with an application, reach control flow transfer for the one or more program instructions, unwind a call stack associated with the one or more program instructions in response to a failure to meet a target control flow, identify an offending function call, and rewrite the offending function call. The rewritten function call includes a memory operation boundary check.
