This is the same issue as in OpenSSH, tracked as CVE-2019-6111.

## Affected

- `libssh < 0.11.4`
- `hardened_images`
- `openshift_container_platform = 4.0`
- `enterprise_linux = 8.0`
- `enterprise_linux = 9.0`
- `enterprise_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `libssh 0.11.4`
