QEMU’s built‑in VNC server contains a deceptively simple bug — a NULL pointer dereference in qemu_clipboard_request() that can be reached by processing a malformed ClientCutText sequence — and the result is a stable, remotely reachable denial‑of‑service that administrators must treat as a...
QEMU’s built‑in VNC server contains a logic error in its clipboard decompression routine that can trap the server process in an infinite loop, allowing a remote, authenticated client to trigger a denial‑of‑service condition by sending specially crafted clipboard data.

I have a windows 7 machine that is currently in audit mode. Like an idiot I didn't create user on it. Is there any way for me to VNC or RDC into the thing? (I have LogMeIn installed).
I've been running into this error when running a VM on my second monitor (with laptop in docking station) and also today when running a VNC connection to another PC in the office.
Hoping someone can help solve this. Reinstalling isn't a viable option right now as it's a company PC, we don't...
So I have a laptop with my entire music library on it, and a desktop with part of my music library on it.
My ipod is synced to my laptop, but what I've found lately is I'll hear a song on my desktop, either add it to a list to download to my laptop later, or download it and use one of many...

Hi guys. New to Windows 7 and have a question. It seems my test machines keep going into some kind of sleep/hibernate state that prevents me from VNC'ing to them. All I want is for the monitors to go to sleep after 15 minutes, but the machines to stay on. We do a lot of work during off...

Using Remote Desktop I can connect my one Win7 machine to my other Win7 machine.
However I don't see my "real" desktop - by that I mean the remote machine spawns a sort of virtual desktop and shows me that - I can't run the graphic card control panel for instance - and if a monitor is plugged...
HTPC underwent a CPU & mem upgrade, went from XP Pro to 7 Ultimate 64bit

I've found that it's much better (in my case) to run without integration features enabled on an XP VM. When I have them enabled, the following happens:
- Can't do Start->Shutdown (it's removed from the menu)
- Sometimes hangs if you click the Close icon (and have it set to shutdown)
- CPU...
