Description Prasad Pandit 2017-06-01 07:24:14 UTC
Quick Emulator built with the USB OHCI Emulation support is vulnerable to an
infinite loop issue. It could occur while processing an endpoint list
descriptor in ohci_service_ed_list().

A guest user/process could use this flaw to crash Qemu process resulting in DoS.
