DoS Vulnerability – Billionaire365

Dash (DASH), Bitcoin Cash (BCH), and Litecoin (LTC) Updated To Tackle the DoS Vulnerability Addressed by the New Bitcoin Core

Dash (DASH) team announced the launch of the new Dash Core 0.12.3.3 to tackle the Denial of Service (DoS) vulnerability addressed Tuesday by the new Bitcoin Core version. Besides Dash (DASH), the teams responsible for Bitcoin Cash (BCH) and Litecoin (LTC) were the first to announce the updates of their software clients and are urging the respective communities of miners to install them as soon as possible.

Dash (DASH) launched Dash Core 0.12.3.3 update

In the case of Dash, the announcement of the update to Dash Core 0.12.3.3, released this Wednesday, notes that it is “correction of a critical bug in the Dash Core 0.12.3.x release series” and explains that the update is related to the Bitcoin Core vulnerability, recently discovered and resolved this Tuesday with the announcement of a new release.

“A major vulnerability was recently discovered in the Bitcoin Core code base that can cause a node that receives a specially forged block with double-spending transactions to crash,” says on the Dash Forum.

Bitcoin Cash (BCH) also updated to tackle the DoS vulnerability

Bitcoin Cash (BCH) client software team, Bitcoin ABC, notified on Tuesday through its Twitter account, soon after the new Bitcoin Core update, that a new version of Bitcoin ABC will be available, correcting “an error” they did not specify.

Most probably, the mysterious “error” they were talking about was also related to the security flaw discovered by Bitcoin (BTC) community of devs and tackled with the Bitcoin Core 0.16.3 version.

Litecoin (LTC) 0.16.3 launched soon after Bitcoin Core

In the case of Litecoin (LTC), it was not necessary to clarify that the new version of its client, published shortly before midnight on Tuesday, was due to the DoS vulnerability discovered in Bitcoin Core, already corrected in the latest version of it.

Litecoin’s development team uses the same terminology in its versions as the Bitcoin Core.

Bitcoin Core 0.16.3 Launched Yesterday To Address A DoS Vulnerability in the Previous Version

A new version of the Bitcoin Core client, the software that identifies valid blocks of the Bitcoin (BTC) blockchain, went live yesterday night, as the Bitcoin Operations Technology Group (Optech) reported on Twitter.

The version of Bitcoin Core 0.16.3 corrects a denial of service (DoS) vulnerability, introduced in version 0.14.0, which had remained undetected until now, and which caused the fall of the Bitcoin Core client by trying to validate a block containing a transaction that attempted to use the same currencies for two different payments, known as a double-spending attack.

In a newsletter addressed to the Bitcoin (BTC) community, Optech explains that after submitting the update yesterday to be reviewed by prominent members of the community, the binary programs of version 0.16.3 were made available yesterday night. Optech recommends that the update should be done immediately.

The newly launched Bitcoin Core 0.16.3 addresses the DoS vulnerability of the previous version

A block containing a double-spending is not allowed by Bitcoin (BTC) blockchain, but the software error blocked the miner or the group of miners trying to validate the malicious block, instead of discarding the block. This progressive blocking effect would have disabled an essential section of the network, leading to a significant decrease in the Bitcoin (BTC) mining hashrate with all the consequent security risks that this entails.

Although a subdirectory of the Bitcoin section in Github describes in detail the procedure for upgrading to Bitcoin Core 0.16.3 and credits the developers Matt Corallo and Suhas Daftuar as responsible for introducing the code to remove the vulnerability, it is not clear who detected the error that could potentially have led to a few issues on Bitcoin (BTC) network.

Optech also reported this Tuesday that the previous version of Bitcoin Core 0.17 is also being updated to include the correction of the DoS vulnerability described above. The availability of Release Candidate 4 of Bitcoin Core 0.17, 0.17RC4, which contains the respective fixes, will soon be announced, says the Optech newsletter.
