SV-45704r1_rule The kernel core dump data directory must be owned by root.

Vulnerability discussion

Kernel core dumps may contain the full contents of system memory at the time of the crash. As the system memory may contain sensitive information, it must be protected accordingly. If the kernel core dump data directory is not owned by root, the core dumps contained in the directory may be subject to unauthorized access.

Check content

Check the ownership of the kernel core dump data directory. # ls -ld /var/crash If the kernel core dump data directory is not owned by root, this is a finding.

Fix text

Change the owner of the kernel core dump data directory to root. # chown root /var/crash

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.
