SV-26614r1_rule The kernel core dump data directory must have mode 0700 or less permissive.

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 mode of the kernel core dump data directory is more permissive than 0700, unauthorized users may be able to view or to modify kernel core dump data files.

Check content

Determine the kernel core dump data directory. # dumpadm | grep "Savecore directory" OR # grep DUMPADM_SAVDIR /etc/dumpadm.conf Check the permissions of the kernel core dump data directory. # ls -l [savecore directory] If the directory has a mode more permissive than 0700, this is a finding.

Fix text

Change the group-owner of the kernel core dump data directory. # chmod 0700 [kernel core dump data directory]

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.
