NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-go.crypto package and not the golang-go.crypto package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

The Go SSH library (x/crypto/ssh) by default does not verify host keys, facilitating man-in-the-middle attacks. Default behavior changed in commit e4e2799 to require explicitly registering a hostkey verification mechanism.
