Check: GEN003522

IRIX 6.5: GEN003522 (in versions v1 r1 through v1 r0.98)

Title

The kernel core dump data directory must have mode 0700 or less permissive. (Cat III impact)

Discussion

Kernel core dumps may contain the full contents of system memory at the time of the crash. As the system memory may contain sensitive information, it must be protected accordingly. If the mode of the kernel core dump data directory is more permissive than 0700, unauthorized users may be able to view or to modify kernel core dump data files.

Check Content

Determine the kernel core dump data directory. Check the permissions of the kernel core dump data directory. # ls -ld /var/adm/crash If the directory has a mode more permissive than 0700, this is a finding.

Fix Text

Change the group-owner of the kernel core dump data directory. # chmod 0700 [kernel core dump data directory]
