Description Prasad Pandit 2017-07-07 09:07:26 UTC
Quick emulator(Qemu) built with the USB redirector support is vulnerable to a
stack buffer overflow flaw. It could occur while logging debug messages when
the debug mode is enabled in the device.

A user/process could use this flaw to crash the Qemu process on the host
resulting in DoS.
