[Qemu-devel] [Bug 1356969] Re: qemu-io: the 'map' command hangs on the fuzzed image

[Max Reitz]

Hi,

well, the issue for this specific image is fixed because it is detected
to be corrupt before the mapping can reach the point in question
(unaligned L2 table entry). However, commit
4b25bbc4c22cf39350b75bd250d568a4d975f7c5 should have fixed the problem
this bug report is really about. Thus, should be fixed.

Thanks for reporting,

Max

Title:
  qemu-io: the 'map' command hangs on the fuzzed image

Status in QEMU:
  Fix Committed

Bug description:
  Sequence:
   1. Unpack the attached archive, make a copy of test.img
   2. Put copy.img and backing_img.vdi in the same directory
   3. Execute

  qemu-io copy.img -c map

  Result: qemu-io processes part of the image and then hangs loading
  100% of CPU time.
