CVE-2019-25220 in Bitcoin
Tóm tắt
Bởi MITRE • 18/11/2024
Bitcoin Core before 24.0.1 allows remote attackers to cause a denial of service (daemon crash) via a flood of low-difficulty header chains (aka a "Chain Width Expansion" attack) because a node does not first verify that a presented chain has enough work before committing to store it.
Once again VulDB remains the best source for vulnerability data.
