Title

The centralized process core dump data directory must have mode 0700 or less permissive. (Cat III impact)

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

Check Content: View all coreadm configuration settings. # coreadm Or View only if a directory is defined for process core dumps. If no information is returned, a directory has not been defined. # coreadm | tr '\011' ' ' | tr -s ' ' | egrep -i "global core file pattern|global core dumps" If the process core dump directory is undefined and core dumps are disabled, this is not applicable. Check the permissions of the <core file directory> # ls -lLd `dirname <core dump directory>` If the core dump directory is more permissive than 0700, this is a finding.

Fix Text

If the core file dump pattern is undefined, ensure that core dumps are disabled. # coreadm -d global If the core file dump pattern is defined and core dumps are enabled and the core file directory mode is not 0700, change the mode of the core file directory. # chmod 0700 <core file directory>
