Return Stack AddressHigh A function returns the address of a stack variable will cause unintended program behavior, typically in the form of a crash. Since a subsequent function call is likely to re-use this same stack address. Common Weakness Enumeration (CWE) ...
A system and method for correcting a hardware return address stack is disclosed. A set of digital comparators examines several locations near the top of the stack and compares them with a calculated return address. If a match is detected, the slot number corresponding to the match is ...

For executable stack: $ gcc -z execstack -o test test.c For non-executable stack: $ gcc -z noexecstack -o test test.c 由于此实验室的目的是表明不可执行的堆栈保护不起作用,因此您应该始终使用此实验室中的“-z noexecstack”选项编译程序。 retlib.c文件 /* This program has a buffer overflo...
Address Sanitizer Error: Use of stack memory after return This check requires code generation that's activated by an extra compiler option,/fsanitize-address-use-after-return, and by setting the environment variableASAN_OPTIONS=detect_stack_use_after_return=1. ...
Address Space Randomization. Ubuntu and several other Linux-based systems use address space randomization to randomize the starting address of heap and stack, making guessing the exact addresses difficult. Guessing addresses is one of the critical steps of bufferoverflow attacks. In this lab, we disa...
