Summary: ntdll/virtual.c:map_image messes up section permissions
                    when sec->Misc.VirtualSize is wrong
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-kernel
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

After mapping sections and performing relocations, map_image goes back to each
section and sets it's image protections to their final values. When doing this,
it calls VIRTUAL_SetProt with size = ROUND_SIZE( sec->VirtualAddress,
sec->Misc.VirtualSize ). If sec->Misc.VirtualSize is less than
sec->SizeOfRawData, this doesn't set the permissions for the entire region,
leaving the permissions of the section "c-rW-". Executable sections don't get
their x bit, and this breaks on systems where read doesn't imply exec.

This breaks Fallout, Fallout 2, and their respective setup programs.
