CVE-2016-4037

From: P J P <ppandit () redhat com>

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 split isochronous transfer descriptor list(siTD) and an infinite loop unfolds if there is a closed loop in this list.

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

This issue is similar to CVE-2015-8558, but using siTD instead of iTD.

Upstream patch: https://lists.gnu.org/archive/html/qemu-devel/2016-04/msg02691.html

This issue are discovered by Du Shaobo of Qihoo 360 Inc.
