SV-60895r2_rule Address Space Layout Randomization (ASLR) must be enabled.

Vulnerability discussion

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 content

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. # sxadm info -p | grep aslr | grep enabled If no output is produced, this is a finding.

Fix text

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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
