This isn&#x27;t a decompression bomb, but here are some fun virtual disk images I found using AFL fuzzer.  One of the files is 329 bytes, but causes qemu to consume 4 GB of heap trying to process it.  This has interesting consequences for the public cloud, where people can upload any old stuff and it is usually processed immediately by &#x27;qemu-img&#x27;.<p><a href="https:&#x2F;&#x2F;bugs.launchpad.net&#x2F;qemu&#x2F;+bug&#x2F;1462949" rel="nofollow">https:&#x2F;&#x2F;bugs.launchpad.net&#x2F;qemu&#x2F;+bug&#x2F;1462949</a><p>(I have a big collection of these, but most of the bugs have now been fixed in qemu)
