SOL-11.1-080110 - The kernel core dump data directory must have mode 0700 or less permissive.

Information

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.

Solution

The root role is required.

This action applies to the global zone only. Determine the zone that you are currently securing.

# zonename

If the command output is "global", this action applies.

Determine the location of the system dump directory.

# dumpadm | grep directory

Change the group-owner of the kernel core dump data directory.

# chmod 0700 [savecore directory]
