Overview
Affected versions of this package are vulnerable to Use After Free via the QIOChannelWebsock object during the WebSocket handshake process. An attacker can cause a denial of service by freeing the object while it is waiting to complete a handshake, which leads to a use-after-free condition when the callback is triggered.
Note:
This is only exploitable if the in-process WebSocket feature is enabled and the attacker has network access to the VNC WebSocket port.
