FreeBSD : qemu -- denial of service vulnerability (a228c7a0-ba66-11e6-b1cf-14dae9d210b8)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Daniel P. Berrange reports :

The VNC server websockets decoder will read and buffer data from
websockets clients until it sees the end of the HTTP headers, as
indicated by \r\n\r\n. In theory this allows a malicious to trick QEMU
into consuming an arbitrary amount of RAM.
