@lorihollasch the note about SEC_IMAGE_NO_EXECUTE in the new AllocationAttributes member description is a bit incomplete. I'm working on adding a new flag for the Flags field that will tell filters whether a SEC_IMAGE section is no-execute. Once that ships and is backported to Germanium branches, Flags will have an additional value: FS_FILTER_SECTION_SYNC_IN_FLAG_IMAGE_NO_EXECUTE (0x00000004).

The way the memory manager works it isn't possible to pass SEC_IMAGE_NO_EXECUTE to the minifilters, hence the new flag.
