Bitcoin Core Patches DoS Vulnerability That Could Crash Bitcoin Core Nodes Nodes

[silversurfer]

The Bitcoin Core Project released Bitcoin Core 0.16.3, an update designed to fix a severe denial-of-service vulnerability which would allow any miner on the Bitcoin network to bring down vulnerable Bitcoin nodes via duplicate input. 

Although the bug did not affect the Bitcoin protocol per se, it did affect all cryptocurrencies built using the Bitcoin Core node software designed to provides bitcoin wallets which thoroughly verify payments.

As advised in the release notes published by the Bitcoin Core developers, all nodes need to be upgraded to the new version by shutting them down and reinstalling using the platform-specific procedure.

The denial-of-service (DoS) vulnerability assigned as CVE-2018-17144 in the security vulnerability database, would allow an attacker, in this case, any miner on the network, to cause a remote denial of service, crashing any vulnerable nodes and disconnecting the network.
