Check: GEN003523

VMware ESX 3 Server: GEN003523 (in version v1 r2)

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 if the kernel core dump data directory has an extended ACL. # ls -lLd <directory> If the permissions contain a '+', the directory has an extended ACL, and this is a finding.

Fix Text

Remove the extended ACL from the kernel core dump data directory.
