How to fix?

Upgrade Alpine:3.12 containerd to version 1.3.3-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream containerd package and not the containerd package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

Go before 1.12.16 and 1.13.x before 1.13.7 (and the crypto/cryptobyte package before 0.0.0-20200124225646-8b5121be2f68 for Go) allows attacks on clients (resulting in a panic) via a malformed X.509 certificate.
