CVE-2016-5126 [HIGH] CWE-120 Qemu: block: iscsi: buffer overflow in iscsi_aio_ioctl
Qemu: block: iscsi: buffer overflow in iscsi_aio_ioctl
Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call.
Quick Emulator(QEMU) built with the Block driver for iSCSI images support (virtio-blk) is vulnerable to a heap-based buffer overflow issue. The flaw could occur while processing iSCSI asynchronous I/O ioctl(2) calls. A user inside a guest could exploit this flaw to crash the QEMU process resulting in denial of service, or potentially leverage it to execute arbitrary code with QEMU-process privileges on the host.

CVE-2016-5126 Qemu: block: iscsi: buffer overflow in iscsi_aio_ioctl
Quick Emulator(Qemu) built with the Block driver for iSCSI images support
(virtio-blk) is vulnerable to a heap buffer overflow flaw. 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.
