A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. A wrong exit condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the inflate_buffer function. This could allow a remote authenticated client who is able to send a clipboard to the VNC server to trigger a denial of service.
