QEMU is vulnerable to denial of service. Quick Emulator(Qemu) built with the Block driver for iSCSI images support (virtio-blk) is vulnerable to a heap buffer overflow issue. It could occur while processing iSCSI asynchronous I/O ioctl(2) calls. A user inside guest could use this flaw to crash the Qemu process resulting in DoS or potentially leverage it to execute arbitrary code with privileges of the Qemu process on the host.
