SV-65247r2_rule Process core dumps must be disabled unless needed.

Vulnerability discussion

A core dump includes a memory image taken at the time the operating system terminates an application. The memory image could contain sensitive data and is generally useful only for developers trying to debug problems.

Check content

To verify that core dumps are disabled for all users, run the following command: $ grep core /etc/security/limits.conf /etc/security/limits.d/*.conf The output should be: * hard core 0 If it is not, this is a finding.

Fix text

To disable core dumps for all users, add the following line to "/etc/security/limits.conf": * hard core 0

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.
