Check: GEN003523

HP-UX 11.31 STIG: GEN003523 (in versions v1 r19 through v1 r13)

Title

The kernel core dump data directory must not have an extended ACL. (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 there is an extended ACL for the kernel core dump data directory, unauthorized users may be able to view or to modify kernel core dump data files.

Check Content

Determine the kernel core dump data directory and check its permissions. # ls -lLd /var/adm/crash If the permissions include a "+" the file has an extended ACL, this is a finding.

Fix Text

Remove the optional ACL from the file. # chacl -z /var/adm/crash
