Description Prasad Pandit 2017-10-11 12:08:03 UTC
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.
