CVE-2020-15112: Etcd

Medium severity, CVSS 6.5. EPSS: 1.3% chance of exploitation in the next 30 days.

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 products

• Etcd Etcd: before 3.3.23 (fixed in 3.3.23); from 3.4.0, before 3.4.10 (fixed in 3.4.10)
• Fedoraproject Fedora: version 32 only
