+Subject: [PATCH] CVE-2015-1779: incrementally decode websocket frames
+
+The logic for decoding websocket frames wants to fully
+decode the frame header and payload, before allowing the
+VNC server to see any of the payload data. There is no
+size limit on websocket payloads, so this allows a
+malicious network client to consume 2^64 bytes in memory
+in QEMU. It can trigger this denial of service before
+the VNC server even performs any authentication.
+
+The fix is to decode the header, and then incrementally
+decode the payload data as it is needed. With this fix
+the websocket decoder will allow at most 4k of data to
+be buffered before decoding and processing payload.
