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.
