VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older was found to
be vulnerable to an unbounded memory allocation issue, as it did not throttle
the framebuffer updates sent to its client. If the client did not consume these
updates, VNC server allocates growing memory to hold onto this data. A malicious
remote VNC client could use this flaw to cause DoS to the server host.
Backport a series of patches from upstream to resolve this.
