CONFIG_COMPAT_BRK: Disable heap randomization

General informations

The Linux kernel configuration item CONFIG_COMPAT_BRK:

Help text

Randomizing heap placement makes heap exploits harder, but it also breaks ancient binaries (including anything libc5 based). This option changes the bootup default to heap randomization disabled, and can be overridden at runtime by setting /proc/sys/kernel/randomize_va_space to 2.

On non-ancient distros (post-2000 ones) N is usually a safe choice.
