$ETH $SOL Not long ago, Bitcoin$BTC developers disclosed information about a software vulnerability that affects about 13% of nodes worldwide. Many analysts said that this poses a serious threat to the blockchain ecosystem. The error with the code CVE-2024-35202, discovered in versions of Bitcoin Core before 25.0, allows attackers to remotely cause a failure in the operation of nodes that process transaction messages (blocktxn).
It involves the use of shortened transfer IDs to reduce traffic, which can cause conflict and lead to system failure. Although the bug was fixed in version 25.0 in May 2023, many nodes have not yet been updated, leaving them vulnerable. The developers urge operators to immediately update their software to version 28.0 to resolve the issue.
An important aspect of the vulnerability is its low financial potential for attackers, since the attack does not allow double spending of bitcoins. However, the possibility of node destruction makes this bug extremely attractive to corporate or government entities looking to destabilize the Bitcoin network.
This is not the first time that serious vulnerabilities have been identified in Bitcoin Core. One of the key issues remains the lack of automatic updates, which forces node operators to track new versions and update the software themselves. If this does not happen, a significant part of the network could be at risk of being disconnected. This continues to worry many cryptocurrency supporters. Thus, timely updates play a critical role in ensuring security, and despite the difficulties with implementation, this process is necessary for the long-term sustainability of the Bitcoin ecosystem.
