Bitcoin Core Developers Disclose High Risk Vulnerabilities in Bitcoin Core Versions 24.0.1 and Below

Odaily Planet Daily News: Bitcoin Core developers have issued a new high-risk warning, stating that one in every six Bitcoin nodes has a software vulnerability. Specifically, all software below Bitcoin Core version 24.0.1 carries risks. According to Bitnodes' monitoring estimates, this denial of service vulnerability has affected approximately 3330 out of 19200 self proclaimed user agents of accessible Bitcoin full nodes. The developers fixed this vulnerability in Bitcoin Core Pull Request (PR) number 25717 and merged it into production on December 12, 2022 with the release of version 24.0.1. The current Bitcoin Core node software version (now 27.1) includes fixes for this vulnerability and other vulnerabilities. Although this vulnerability is quite serious, there are few known cases of attacks exploiting it in public records. Due to the high cost of generating and broadcasting block header chains to perform denial of service attacks, this vulnerability has almost no economic benefit for attackers. （Protos）
