Address Space Layout Randomization (ASLR) must be enabled.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-48023	SOL-11.1-080030	SV-60895r3_rule		Low

Description
Modification of memory area can result in executable code vulnerabilities. ASLR can reduce the likelihood of these attacks. ASLR activates the randomization of key areas of the process such as stack, brk-based heap, memory mappings, and so forth.

Check Text ( C-50459r3_chk )
This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this check applies. Determine if address space layout randomization is enabled. Determine the OS version you are currently securing:. # uname –v For Solaris 11, 11.1, 11.2, and 11.3: # sxadm info -p \| grep aslr \| grep enabled For Solaris 11.4 or newer: # sxadm status -p -o status aslr \| grep enabled If no output is produced, this is a finding.

Check Text ( C-50459r3_chk )

This check applies to the global zone only.

Determine the zone that you are currently securing.

# zonename

If the command output is "global", this check applies.

Determine if address space layout randomization is enabled.

Determine the OS version you are currently securing:.
# uname –v

For Solaris 11, 11.1, 11.2, and 11.3:
# sxadm info -p | grep aslr | grep enabled

For Solaris 11.4 or newer:
# sxadm status -p -o status aslr | grep enabled

If no output is produced, this is a finding.

The root role is required. This action applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this action applies. Enable address space layout randomization. # sxadm delcust aslr Enabling ASLR may affect the function or stability of some applications, including those that use Solaris Intimate Shared Memory features.
