Ensure 'Disable additional security checks on VBA library references that may refer to unsafe locations on the local machine' is set to 'Disabled'

설명

This policy setting restricts VBA to checking project library references only against the registry and trusted zones. The recommended state for this setting is: Disabled Rationale: A remote code execution vulnerability exists when Microsoft Office improperly loads arbitrary type libraries. An attacker could then install programs, view, change, or delete data, or create new accounts with full user rights. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\vba\security:disablestrictvbarefssecurity (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 0. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
