Vulnerability Title
Qemu: vnc: null pointer dereference in qemu_clipboard_request()
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service.
