Information

The operating system must implement address space layout randomization to protect its memory from unauthorized code execution.

GROUP ID: V-270772
RULE ID: SV-270772r1066805

Some adversaries launch attacks with the intent of executing code in nonexecutable regions of memory or in prohibited memory locations. Security safeguards employed to protect memory include, for example, data execution prevention and address space layout randomization. Data execution prevention safeguards can either be hardware-enforced or software-enforced with hardware providing the greater strength of mechanism.

Examples of attacks are buffer overflow attacks.

Solution

Remove the "kernel.randomize_va_space" entry found in the "/etc/sysctl.conf" file or any file located in the "/etc/sysctl.d/" directory.

After the line has been removed, the kernel settings from all system configuration files must be reloaded before any of the changes will take effect. Run the following command to reload all of the kernel system configuration files:

$ sudo sysctl --system
