Bitcoin Core developers fix 5-year-old disk fill vulnerability

Odaily News The Bitcoin Core development team this month fixed a disk filling vulnerability that has plagued full node operators for five years. The vulnerability allows attackers to force node hard disks to continuously write redundant data through malicious log instructions (such as LogPrintf, LogInfo, LogWarning, or LogError, etc.), causing serious impacts on mechanical hard disk nodes and even causing performance degradation of flash memory devices.
The fix was submitted via PR 32604, and developers expect that the disk filling attack will completely disappear after the patch is popularized with the new version of Bitcoin Core on the Bitcoin network. The latest version of Bitcoin Core is 29.0, released on April 14, 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. (Protos)
