            Bug ID: 230782
           Summary: Explicitly deny 'system-privilege' in the sandbox
                    profile as a hardening measure
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

Although we do not need 'system-privilege', the default sandbox state includes it as a backwards-compatibility affordance.

Update our sandboxes to tell the kernel we don't need the support, except for the one case in the Networking process.
