Merge bitcoin/bitcoin#22146: Reject invalid coin height and output index when loading assumeutxo
fa9ebedec3f982bb5bb459ea33d74c94d9b5cec4 Reject invalid coin height and output index when loading assumeutxo (MarcoFalke)
Pull request description:
It should be impossible to have a coin at a height higher than the height of the snapshot block, so reject those early to avoid integer wraparounds and hash collisions later on.
Same for the outpoint index.
Both issues were found by fuzzing:
* The height issue by OSS-Fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34793
* The outpoint issue by my fuzz server: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34793#c2
