What is CVE-2016-10725?

In Bitcoin Core versions prior to v0.13.0, a design flaw in the alert system allows non-final alerts to obstruct final alerts, which are intended to take precedence and override all other notifications. This flaw arises from incorrect operational sequencing in the deprecated remote network alert system. This issue is not isolated to Bitcoin Core; it also affects Bitcoin Knots and a variety of alternative cryptocurrencies that utilize the same code foundation.
