Check: GEN003523

IRIX 6.5: GEN003523 (in versions v1 r1 through v1 r0.98)

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. Check the kernel core dump data directory permissions. # ls -ldD /var/adm/crash If the file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the file. # chmod A- [kernel core dump directory]
