           Summary: Audit V8 bindings for
                    V8Proxy::retrieveFrameForEnteredContext
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: abarth at webkit.org
                CC: aa at chromium.org


In the V8 bindings, we use V8Proxy::retrieveFrameForEnteredContext in a bunch
of places were we should be using retrieveFrameForCurrentContext.  We should
audit all these call sites and make sure they match JavaScriptCore.  Match in
this context is:

retrieveFrameForEnteredContext <-> exec->dynamicGlobalObject
retrieveFrameForCurrentContext <-> exec->lexicalGlobalObject

Getting this right is important for security and subtle for compatibility.
