== Huge header size ==
Formatting 'TEST_DIR/t.IMGFMT', fmt=IMGFMT size=67108864

qcow2: Check backing_file_offset (CVE-2014-0144) Header, header extension and the backing file name must all be stored in the first cluster. Setting the backing file to a much higher value allowed header extensions to become much bigger than we want them to be (unbounded allocation).

qcow2: Check refcount table size (CVE-2014-0144) Limit the in-memory reference count table size to 8 MB, it's enough in practice. This fixes an unbounded allocation as well as a buffer overflow in qcow2_refcount_init().
