Title

Process core dumps must be disabled unless needed. (Cat III impact)

Discussion

Process core dumps contain the memory in use by the process when it crashed. Process core dump files can be of significant size and their use can result in file systems filling to capacity, which may result in Denial of Service. Process core dumps can be useful for software debugging.

Check Content

Check the process core dump configuration. # coreadm |grep enabled OR # egrep "COREADM_.*_ENABLED" /etc/coreadm.conf. If any lines are returned by coreadm or if any lines are not set to no in /etc/coreadm.conf, this is a finding. # grep coredumpsize /etc/system If the value is 1, this is a finding.

Fix Text

Change the process core dump configuration. # coreadm -d global # coreadm -d process # coreadm -d global-setid # coreadm -d proc-setid # coreadm -d log Edit /etc/system and remove the coredumpsize parameter.
