My best guess is that these have been truncated. Having a look with
{{org.apache.poi.poifs.dev.POIFSHeaderDumper}} it certainly looks that way

> We're getting around 300 exceptions from "application/x-tika-msoffice" files
> in our current slice of Common Crawl documents that look roughly like this:
> {noformat}
> java.lang.IllegalArgumentException: Position 86528 past the end of the file
> at org.apache.poi.poifs.nio.FileBackedDataSource.read
> {noformat}
> I suspect these are non-MS OLE file formats. Any help identifying the file
> types and patching our OLE mime detector would be great.
