Zusammenfassung:This disclosure is directed to binary translator driven program state relocation. In general, a device may protect vulnerable program functions by setting them as non-executable. If an attempt is made to execute a protected program function, the program may trap to a binary translator in the device that may be configured to relocate program state from what has already been established (e.g., on a stack register). Program state may include resources (e.g., memory locations) used by the program during the course of execution. The binary translator may then translate the program into an executable form based on the relocated program state, and may be executed accordingly. Intruding code that attempts to overcome normal program execution and implement hostile operations (e.g., based the program state that is reflected in the stack register) will not function as intended since the relocated program state will cause unexpected results.
