Odaily Planet Daily 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 impact on mechanical hard disk nodes and even causing flash memory device performance degradation.
This fix was submitted through PR 32604. Developers expect that after the patch is popularized in the Bitcoin network with the new version of Bitcoin Core, the disk filling attack will disappear completely. 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)
