Bitcoin Core developers fix 5-year old disk stuffing vulnerability

According to Protos, the Bitcoin Core development team this month fixed a disk stuffing vulnerability that had plagued all node operators for five years. This vulnerability allows attackers to force node hard drives to continuously write redundant data through malicious log commands such as LogPrintf, LogInfo, LogWarning, or LogError, causing serious impact on mechanical hard drive nodes and even leading to performance degradation of flash devices. This fix was submitted through PR 32604 and merged into the main branch by experienced developer Gloria Zhao. The submission passed 19 checks and had no objections. Developers expect that disk stuffing attacks will completely disappear with the popularity of the new version of Bitcoin Core on the Bitcoin network. The latest version of Bitcoin Core is 29.0, released on April 14th, and the Core version is usually upgraded every few months. As a voluntary software package that does not allow automatic updates, full node operators must always choose to manually upgrade their software. About 16% of node operators are running version 29.0. The other nodes are running old versions of software.
