CWE-770  (opens in a new tab)

How to fix?

Upgrade Debian:8 qemu to version 1:2.1+dfsg-12+deb8u7 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:8 relevant fixed versions and status.

The xhci_ring_fetch function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit the number of link Transfer Request Blocks (TRB) to process.
