Descriptions

stack_protect_prologue in cfgexpand.c and stack_protect_epilogue in function.c in GNU Compiler Collection (GCC) 4.1 through 8 (under certain circumstances) generate instruction sequences when targeting ARM targets that spill the address of the stack protector guard, which allows an attacker to bypass the protection of -fstack-protector, -fstack-protector-all, -fstack-protector-strong, and -fstack-protector-explicit against stack overflow by controlling what the stack canary is compared against.

stack_protect_prologue en cfgexpand.c y stack_protect_epilogue en function.c en GNU Compiler Collection (GCC) 4.1 a 8 (bajo ciertas circunstancias) genera secuencias de instrucciones al apuntar a objetivos ARM que derraman la dirección del protector de pila, que permite al atacante eludir el la protección de -fstack-protector, -fstack-protector-all, -fstack-protector-strong y -fstack-protector-explicit contra el desbordamiento de pila controlando contra qué se compara la pila Canary.
