Описание
Buffer overflow in the send_control_msg function in hw/char/virtio-serial-bus.c in QEMU before 2.4.0 allows guest users to cause a denial of service (QEMU process crash) via a crafted virtio control message.
Qemu emulator built with the virtio-serial vmchannel support is vulnerable to a buffer overflow issue, while exchanging virtio control messages between guest & the host. A malicious guest could use this flaw to corrupt few bytes of Qemu memory area, potentially crashing the Qemu process.
