Because alerts are identified by their hashes, changing the ommitted fields allows an Alert to be classified as a final alert but still be an alert that is added to the infinitely sized map. Although the final alert is supposed to be uncancellable, it unfortunately is cancellable due to the order of actions when processing an alert. Alerts are first processed by checking whether they cancel any existing alert. Then they are checked whether any of the remaining alerts cancels it.
Because of this order, it is possible to create an alert which cancels a final alert before the node checks whether that alert is canceled by the final alert. Thus an attacker can cancel a final alert with another alert allowing a node to be vulnerable to all of the aforementioned attacks. Fixing these issues is relatively easy. The first and most obvious solution is to simply remove the Alert system entirely.
As nodes upgrade to versions without the Alert system, fewer nodes will be vulnerable to attack should the Alert keys become public. This is the option that Bitcoin has taken.
However, because Bitcoin has retired the Alert system entirely, the Alert key will also be published to reduce the risk that the Alert Key is mistakenly depended upon in the future.
Should altcoins wish to continue using the Alert system but with a different Alert Key, a few very simple fixes will safeguard nodes from the aforementioned issues. Limiting the number of alerts, the size of setCancel and setSubVer , and only allowing one final alert altogether fix the above issues. This patch , on top of Bitcoin Core 0.
