Title

The centralized process core dump data directory must be owned by root. (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 centralized process core dump data directory is not owned by root, the core dumps contained in the directory may be subject to unauthorized access.

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. To check the ownership of the <core file directory>, substitute the global core file pattern from the above command into the next command. # ls -lLd `dirname <global core file pattern>` If the directory is not owned by root, 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 is not group-owned by root, bin, sys or other, change the owner of the core file directory. # chown root <core file directory>
