Subject: [oss-security] CVE request Qemu: usb: infinite loop in ehci_advance_state results in DoS

   Hello,

Qemu emulator built with the USB EHCI emulation support is vulnerable to an 
infinite loop issue. It occurs during communication between host controller 
interface(EHCI) and a respective device driver. These two communicate via a 
isochronous transfer descriptor list(iTD) and an infinite loop unfolds if 
there is a closed loop in this list.

A privileges user inside guest could use this flaw to consume excessive CPU 
cycles & resources on the host.

Upstream fix:
- -------------
   -> https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg02124.html

This issue was discovered by Qinghao Tang of QIHU 360 Marvel Team.

Thank you.
