Earlier this week, steemit was informed of a potential vulnerability in steemd that could lead to a denial of service attack in both the API and P2P layers of steemd, but has absolutely no impact on the cryptography securing the Steem blockchain.
This threat did not create any risk to Steem accounts or token balances, however, our engineers quickly located the problem and fixed it. The patch was deployed to steemit's Steem nodes within 24 hours of discovering the bug. We have contacted witnesses to update their seed and witness nodes to preserve the stability of the P2P network and are in the process of informing exchanges to ensure their continuous operation. The patch doesn't require a replay; Node operators should simply update and restart steemd.
At this time, we do not believe the vulnerability is being actively exploited in any sort of attack, however, we recommend anyone running a steemd node upgrade to the newest version of stable. This can be done via docker pull steemit/steem using our provided Docker image.

How do I update my witness please?
If you are not running a witness server, then you don’t have to worry about it.
Good to hear you are on the case. Security is a constant battle and Steemit is sure to come under attack as it gets more popular. Some of us remember a previous assault. At least we had some other options to access the blockchain.
It's like a game of whack-a-mole, isn't it? The moment you patch one hole, another one shows up...
@Curie 's Witness/Seed has been updated, Cheers.
My witness, backup witness, seed and rpc nodes have all been updated now :)
Dear @ausbitbank;
I need any help to stop @grumpycat hurting innocent people.
We have to show that Steemit is bigger than any bully who is trying to impose his own rules by using his high SP on innocent people.
The post below is the summary of the situation :

It's reassuring to hear that there was such a quick and robust response before this vulnerability was exploited, good job to everyone involved!
My server has been updated, thank you.
.
Thank you for looking after the community, the investments and the tech!
That's a relief. Thanks for the info
I LOVE knowing that you guys are on it. Thank you.
Thats a great news...at least we have wonderful engineers. Thanks for info
Who informed?
Where informed ?
Could you refer to an issue or PR, please.
Wow, i am glad the probem was identified on time and fixed. Thanks for the important update
could you explain how to do this o.O!!!!!!!!!!!!!
Kudos to the engineers for a timely intervention.
We are unstoppable.
Thanks so much for keeping us informed as quickly as possible of threats to Steemd security. Much appreciated!
Ok. We totally understand that there will always be security risks. Now we can rest assured that your security team is actively in control. We shall keep steeming
This isn't responsible for the network slowing down for about half the day each day, is it? Bandwidth seems to get crushed around the same hours all the time.
Bandwidth is unrelated.
A DoS is not so bad unless it lasts a lot. It is great to hear that it is fixed now, you are moving fast, guys, great job!
good job guys.
Cryptwo Witness node has been all updated
Thanks for sharing this information.
Good thing your on top of things guys. Good job
Suggestion, could it be added a check, verification, who of witnesses did update and give us voters this information on that witness web page, so we voters can ask 'our' witness to do their job or we can take votes away from the ones not doing update. Could this be done?
Kudos to all the engineers working around the clock to keep the Steem/Steemit platform safe.
In these days of volatile digital vulnerabilities, your tasks are no easy jobs! You guys and ladies rock.
