How to fix?

Upgrade Debian:unstable qemu to version 1:2.8+dfsg-7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The qemu-nbd server in QEMU (aka Quick Emulator), when built with the Network Block Device (NBD) Server support, allows remote attackers to cause a denial of service (segmentation fault and server crash) by leveraging failure to ensure that all initialization occurs before talking to a client in the nbd_negotiate function.
