QEMU: I/O: potential memory exhaustion via websock connection to VNC
Qemu through 2.10.0 allows remote attackers to cause a memory leak by triggering slow data-channel read operations, related to io/channel-websock.c.
A memory leakage issue was found in the I/O channels websockets implementation of the Quick Emulator (QEMU). 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 denial of service on the host and/or potentially crash the QEMU process instance on the host.

CVE-2017-15268 QEMU: I/O: potential memory exhaustion via websock connection to VNC
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.
