| Mauro Matteo Cascella | 2023-06-29 10:14:27 UTC | Doc Text | 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, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. A remote unauthenticated client could use this flaw to cause a denial of service. | |
