The SLES for vRealize must implement address space layout randomization to protect its memory from unauthorized code execution.


Finding ID Version Rule ID IA Controls Severity
V-240521 VRAU-SL-001340 SV-240521r852582_rule Medium
Some adversaries launch attacks with the intent of executing code in non-executable regions of memory or in memory locations that are prohibited. 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.

Check Text ( C-43754r671302_chk )
Verify "randomize_va_space" has not been changed from the default "1" setting.

# sysctl kernel.randomize_va_space

If the return value is not "kernel.randomize_va_space = 1", this is a finding.
Fix Text (F-43713r671303_fix)
Run the following command:

#sysctl kernel.randomize_va_space=1
