> The following snippet will cause an OOM as it tries to allocate a huge
> byte-array.
>
> {code:java}
> byte[] input =
> java.util.Base64.getDecoder().decode("iVBORw0KGgoAAAAbaUNDUMlDQyCrbAAtGHZwQWdQyUNDIKtsAAAYiVBORw0KGgp1AAAASURBVA0KGgoAAAANSUhEUgAAACAAIAQACAJ/2QAAsnMAAAAAAElFTkRCYAAY");
> Imaging.getAllBufferedImages(input); {code}
> All such allocations should be guarded by some limits, see e.g.
> [https://poi.apache.org/apidocs/dev/org/apache/poi/util/IOUtils.html#safelyAllocate-long-int-]
> for how Apache POI supports a configurable limit for allocations.
