Description Agostino Sarubbo gentoo-dev 2017-07-07 09:22:52 UTC
From ${URL} :

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.

Upstream patch:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
