Security vulnerabilities and automated fixes for preprocessor macros issues
1 post found
A critical vulnerability in DeepSkyStackerKernel's StackWalker.cpp was silently replacing bounds-checking string functions with their unsafe counterparts via preprocessor macros, exposing the entire codebase to buffer overflow attacks. This fix removes the dangerous macro definitions that discarded buffer size arguments, restoring the intended memory safety protections across all call sites. Understanding how this subtle macro trick works is essential for any C/C++ developer working with string
