CVE-2023-6683
Qemu: vnc: null pointer dereference in qemu_clipboard_request()
Résumé
Qemu: vnc: null pointer dereference in qemu_clipboard_request()
Description d'origine
La description telle que publiée par la source (souvent en anglais).
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.
