How to fix?

Upgrade Debian:unstable qemu to version 1:2.6+dfsg-1 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 ohci_bus_start function in the USB OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors related to multiple eof_timers.
