QEMU: VNC: improper I/O watch removal in TLS handshake can lead to remote unauthenticated denial of service

A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QE...
