Title

The centralized process core dump data directory must not have an extended ACL. (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 an extended ACL, unauthorized users may be able to view or to modify sensitive information contained any process core dumps in the directory.

Check Content

Check the defined directory for process core dumps. # coreadm | grep "global core file pattern" OR # grep COREADM_GLOB_PATTERN /etc/coreadm.conf Check the permissions of the directory. # ls -lLd [core file directory] If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the directory. # chmod A- [core file directory]
