Security Patch Announcement

over 8 years ago (Edited)

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.

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 :

Thank you for any help to stop the actions of @grumpycat.

Best Regards.

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.

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.

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?
