Description Agostino Sarubbo gentoo-dev 2017-10-12 06:40:15 UTC
From ${URL} :

Quick Emulator(Qemu) built with the I/O channels websockets support is 
vulnerable to a memory leakage issue. It could occur while sending screen 
updates to a client, which is slow to read and process them further.

A privileged guest user could use this flaw to cause a DoS on the host and/or 
potentially crash the Qemu process instance on the host.

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.
