NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm-block-iscsi package and not the qemu-kvm-block-iscsi package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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.
