Researcher's Death Hampers TCP Flaw Fix
linuxwrangler writes "Security researcher Jack Louis, who had discovered several serious security flaws in TCP software was killed in a fire on the ides of March, dealing a blow to efforts to repair the problem. Although he kept good notes and had communicated with a number of vendors, he died before fixes could be created and prior to completing research on a number of additional vulnerabilities. Much of the work has been taken over by Louis' friend and long-time colleague Robert E. Lee. The flaws have been around for a long time and would allow a low-bandwidth 'sockstress' attack to knock large machines off the net."
Or was he silenced?

Is there anything Robert E. Lee CAN'T do?

Clearly this was the result of a conspiracy by veterans of the civil war. I hope the other researchers, Grant and Lincoln, hear about this.
It is by the juice of the coffee bean that thoughts acquire speed, the teeth acquire stains. The stains become a warning
Was it necessary to refer to his colleague as Robert E. Lee? Now we're going to get a ton of "South will rise again" jokes.
Less than a week ago is was Rick752. Now this one. Definitely reinforces the importance of collaboration, and the fragile nature of ideas.

... so I guess this guy passing away shouldn't make us too worried.
It's like his lungs were DoSed.

It's not a joke when you tell someone to DIAF on the Internet. What if someone told him that before he died? Think of how guilty they'd feel now!

That was my first thought reading the summary. I mean come on:
The Ides of March
Colleague "Robert E Lee"
Low bandwidth attack that can take down large servers?
I suppose we should all beware the Ides of March. Et tu, Bruce Schneier, et tu?
He should have bewared the Ides of March.
Exactly what I thought when I first read this. There is just to much seemingly made up stuff in the story. He died on the ides of March, his colleague is Robert E. Lee, and even his name seems made up for some reason. I went so far as to check out his facebook memorial and this still seems off to me.
Still condolences to his family.
So a good scientist dies and all Slashdotters can do is attempt whoring out a +5 Funny with lame jokes?
:(
My high regard for the Slashdot community is obviously misguided.
It's a great loss for the research community and my condolences go to his family. And really, that's a nasty way to go...
I thought you Americans did win that one?
Well, everyone's having a good laugh at the expense of the death of this guy. May as well laugh at a picture of him.
This is my sig.
This problem was demonstrated in 2000, with the NAPTHA software and its demonstration that the problem is not academic. Yes, before NAPTHA, there was some software that could demonstrate the issue but this software had issues itself (written in perl, kept state) which limited its effectiveness. SockStress is just NAPTHA revisited.
I have a fix for this problem, but there's not enough room in the margin to describe it.
You would think someone like that would have a firewall.
Someone really smart died in a fire, I am so sorry for your family, a great loss for humanity :(
Estoy contento de estar vivo, gracias!
How can we get these secrets of the vulnerabilities back form the general?!
Comment whoring for +1 funny mods is like pimping out your girlfriend for monopoly money.
he had NO firewall.
I apologize for that joke. I realize I will burn in hell for that one.

The attack is very real.

It's a shame he had to die that way, burning to death must be horrible. I can also understand why there's going to be such a delay in fixing the TCP/IP issue: nobody ever plans for a developer being caught in a fire. Now, if he'd only managed to get hit by a bus, everything would have been OK, because everybody plans for that.

TCP is not software.
Its got software implementations, but still. Not Software.
Death Hampers!

Meh. According to the link, Sockstress is simply making lots of completed TCP connections to the target. The "sneaky trick" is apparently just doing it raw, so the client OS doesn't waste memory tracking them.
Probably the other worlds need TCP/IP fixes more than Earth.

...just use connlimit. There are some slight flaws in it but there is certainly no need to allow someone to open a thousand connections.

Very sad indeed!
Lets just say Heaven needed a TCP/IP fix and called him there.
And the security fix they were working on is to replace your firewall with a Stonewall (the brand name for this device, curously enough, is Jackson).

Phew. Good thing I went with only 1U servers.
I don't think this is about how simple it is, but how hard it is to fix it, because that is the real problem. If people only need a simple DSL to DOS a server, this is bad news. Obviously, you can limit per IP, but DDOS also becomes much easier this way.
So that's why I think it's very real, more real than say the whole BGP-security stuff. Yes it does happen and the impact might be big, but there are some fixes. But this might be a lot harder to fix.
New things are always on the horizon
Why is it that every description of this problem that I've read so far does not present a problem.
The sockstresss.com itself provides a horrible description of it in the front page. All it appears to do is open up multiple tcp sockets.
Apparently the source IPs are not spoofed, thus the syn cookies are not at play, so how can it not hit a max connections per source IP? Any tcp service worth didley must use that in some form or the other.
If someone has some (f)actual information about this, please, provide a few links...
