Description

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

• etcd etcd (< 3.3.23) • etcd etcd (>= 3.4.0 < 3.4.10) • fedoraproject fedora 32
