In etcd before versions 3.3.23 and 3.4.10, it is possible to have an entry index greater then the number of entries in the ReadAll method in wal/wal.go. This could cause issues when WAL entries are being read during consensus as an arbitrary etcd consensus participant could go down from a runtime panic when reading the entry.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| go/go.etcd.io/etcd/v3 | lt | 3.3.23 | |
| go/go.etcd.io/etcd/v3 | ge | 3.4.0 | |
| go/go.etcd.io/etcd/v3 | lt | 3.4.10 |
