You should take immediate action to stop any damage or prevent further damage from happening. Description This signature detects an attempt to exploit a buffer overflow vulnerability in UltraVNC. Additional Information UltraVNC is a client/server remote access suite that allows remote users to access desktops as though they are a local user.UltraVNC is susceptible to multiple error-logging remote buffer-overflow vulnerabilities. The application fails to properly bounds-check user-supplied input before copying it to insufficiently sized memory buffers.The first issue is in the client-based 'Log::ReallyPrint()' function in the 'vncviewer/Log.cpp' source file. This function is responsible for logging remote error messages from servers. The vulnerable function uses a 1024-byte memory buffer to receive error messages from the server; if a server returns excessive error message data, adjacent memory will be overrun with attacker-supplied data.The second issue is in the server-based 'VNCLog::ReallyPrint()' function in the 'wi

I just installed Norton 360 on 3 computers in my home. Norton 360 configured everything automatically and Real VNC was working for a very short time. norton vnc large For some reason, everything stopped working and I can no longer connect to any computer on my network that has Norton 360 installed. I ve tried manually opening the correct port with no luck on all computers. Is there a way to disable automatic configuration so that I can get a prompt that ask if I want to deny or allow inbound or outbound connections? I've never had issues like this with a firewall. Having a tight firewall is good and all, but if I continue to have issues like this, I see no reason to use this service.

01:27 PMI have a VPS on which I'm running Ubuntu 13.04 64 bit currently .. I've installed tightvncserver on it, and then I access the VPS through a VNC connection .. The problem is that when I boot the VPS, and manually activate the VNC server on the VPS (via putty), from that point, the VNC connection only works for about 15-20 minutes ... After that, VNC no longer works, and to get it to work, I have to restart the VPS and repeat .. Note that even when VNC stops responding, the VPS itself and all its applications are still running .. I know this because I use those application's web interfaces, and they all respond fine .. Putty works too .. Only VNC stops responding after a little while .. After the said time, any existing VNC connection just stops, and if I try reconnecting VNC, it just says "Too many security failures" or "Too many authentication failures" .. I had 11.04 64 bit installed before, and the problem was on that too .. Anyone know what's causing this ? steeldriverAugust 11th, 2013, 01:32 PMAre you tunneling the VNC over SSH? if not maybe it is getting flooded by malicious connection attempts? ahmadkaAugust 11th, 2013, 02:01 PMNope I'm not tunneling anything, I think ... I use putty to just start the server, and then I separately start Real VNC Viewer on my PC, and use XXX.XXX.XXX.XXX:1 to start the VNC connection .. Also, this problem started like a month ago maybe .. Before that it was fine .. Also, sometimes when I try to connecting, Norton Internet Security 2013 gives me a message that it protected me from some hack attempt "VNC Large Error Response CVE-2001-0167" How can I fix this ? steeldriverAugust 11th, 2013, 02:15 PMTunnel Don't expose ANY insecure ports on a public facing interface Add the -localhost flag to your vncserver invocation and/or close the VNC port on the VPS with ufw or iptables (in fact, best to drop all incoming traffic by default and just open your SSH port - but remember to add and verify the 'allow SSH' rule BEFORE enabling ufw else you will lock yourself out completely) Then set up a tunnel using PuTTY - the port-to-display naming convention for VNC is that display :n uses port (5900+n) i.e. for your display :1 you would tunnel to localhost:5901 (remember 'localhost' is actually the remote host in the context of the tunnel). The local port can be any free port but it keeps things simple if you use L5901. Then point your VNC viewer at localhost:5901 ahmadkaAugust 11th, 2013, 02:29 PMI get the first part, about how you're saying I should limit vnc
