Vulnerability discussion

Process core dumps contain the memory in use by the process when it crashed. Any data the process was handling may be contained in the core file, and it must be protected accordingly. If the process core dump data directory has a mode more permissive than 0700, unauthorized users may be able to view or to modify sensitive information contained any process core dumps in the directory.

Check content

Procedure: Check the defined directory for process core dumps. # cat /proc/sys/kernel/core_pattern|xargs -n1 -IPATTERN dirname PATTERN Check the permissions of the directory. # ls -lLd If the has a mode more permissive than 0700, this is a finding.

Fix text

Change the mode of the core file directory. # chmod 0700

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.
