Odaily Planet Daily News Bitcoin Core development team has fixed a disk filling vulnerability that has plagued full node operators for five years this month. This vulnerability allowed attackers to force node hard drives to continuously write redundant data through malicious log instructions (such as LogPrintf, LogInfo, LogWarning, or LogError), causing severe impact on mechanical hard drive nodes and even leading to performance degradation of flash storage devices. The fix was submitted through PR 32604, and developers expect that with the new version of Bitcoin Core being widely adopted on the Bitcoin network, disk filling attacks will completely disappear. The latest version of Bitcoin Core is 29.0, released on April 14, and Core versions are typically upgraded every few months. As a voluntary package that does not allow for automatic updates, full node operators must always choose to manually upgrade their software. (Protos)
