-Subject: [spice-server 1/3] reds: Disconnect when receiving overly big
- ClientMonitorsConfig
-
-Total message size received from the client was unlimited. There is
-a 2kiB size check on individual agent messages, but the MonitorsConfig
-message can be split in multiple chunks, and the size of the
-non-chunked MonitorsConfig message was never checked. This could easily
-lead to memory exhaustion on the host.

-It was also possible for a malicious client to set
-VDAgentMonitorsConfig::num_of_monitors to a number larger
-than the actual size of VDAgentMOnitorsConfig::monitors.
-This would lead to buffer overflows, which could allow the guest to
-read part of the host memory. This might cause write overflows in the
-host as well, but controlling the content of such buffers seems
-complicated.
