Descriptions
The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits.
La función arch_pick_mmap_layout en arch/x86/mm/mmap.c en el kernel de Linux hasta la versión 4.5.2 no maneja de forma aleatoria el legado de la dirección base, lo que hace más fácil a usuarios locales romper las restricciones destinadas en los indicadores ADDR_NO_RANDOMIZE, y eludir el mecanismo de protección ASLR para programas setuid o setid, deshabilitando los límites de recursos del consumo de pila.
A weakness was found in the Linux ASLR implementation. Any user able to running 32-bit applications in a x86 machine can disable ASLR by setting the RLIMIT_STACK resource to unlimited.
