CVE-2020-15112 is fixed in 4 products on 1 platform, first by etcd 3.2.17+dfsg-1ubuntu0.1~esm1, released August 6, 2020. It is not reported as exploited. Patch Radar priority: Routine.
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.
