Check: GEN003523
AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE:
GEN003523
(in versions v1 r14 through v1 r10)
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 core file copy location from the sysdumpdev command. #sysdumpdev -l | grep -I "core dir" Determine if the kernel core dump data directory has an extended ACL. #aclget < directory > Verify if extended permissions are disabled. If extended permissions are not disabled, this is a finding.
Fix Text
Remove the extended ACL from the kernel core dump data directory and disable extended permissions. #acledit < directory >
