Title

Process core dumps must be disabled unless needed. (Cat II 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 If any lines are returned by coreadm other than "logging", this is a finding.

Fix Text

The Maintenance and Repair profile is required. Change the process core dump configuration to disable core dumps globally and on a per process basis. # coreadm -d global # coreadm -d process # coreadm -d global-setid # coreadm -d proc-setid # coreadm -e log
