            Bug ID: 263506
           Summary: Make sensitive jsc global namespace properties not
                    enumerable by Object.getOwnPropertyNames.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

Some functions in the jsc shell GlobalObject are only added as debugging aids.  They are meant to be used carefully under controlled conditions for test development.  Though they are added as DontEnum, Object.getOwnPropertyNames() still enumerates them.  We should filter out all DontEnum properties of this GlobalObject so as not to trip up fuzzers that try to fuzz with Object.getOwnPropertyNames.
