A null pointer dereference issue was found in the IDE disk emulator of QEMU. It could occur while cancelling an i/o operation via ide_cancel_dma_sync() routine, if a block drive pointer is null. A guest may use this flaw to crash the QEMU process on the host resulting in DoS scenario.

Created qemu tracking bugs for this issue:
Affects: fedora-all [bug 1883453]
Created xen tracking bugs for this issue:
Affects: fedora-all [bug 1883454]
In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP qemu-kvm-rhev package.
