Security Patch Announcement
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.

Wow, i am glad the probem was identified on time and fixed. Thanks for the important update
Thank you for looking after the community, the investments and the tech!
My witness, backup witness, seed and rpc nodes have all been updated now :)
That's a relief. Thanks for the info
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.
All my servers and services have been updated with the updated code.
Good work Steem Team!
Witness updated. Thanks
All my servers already updated.
Updated and running smoothly. Thank you for a quick turn around of fixing the issue.

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
It's been done for a while now. Thanks for the official post.
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.
Already updated seed and witness nodes.
keep up the updates:P
Witness updated!
Way to go, guys!
How can we explore the next steemit updates? I would like to know what you guys working at in the near future...

All jacked up and good to go!
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 nodes are updated.
@Curie 's Witness/Seed has been updated, Cheers.
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?

Bandwidth is unrelated.
If you are not running a witness server, then you don’t have to worry about it.

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 :
