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

Coreadm is not available for HP-UX 11i versions prior to 11i-v3 (11.31). When a core dump occurs on 11i-v2, the core is placed in the program's working directory. In order to implement this feature of coreadm, the filesystem would have to be traversed (on a virtually continuous basis) in order to locate a corefile and move it to a manually configured core directory. As there is a prior requirement to disable core dumps via V-11996: # echo "ulimit -c 0" >> /etc/profile This check is currently not applicable to HP-UX 11i-v2.
