CVE-2017-3204: Go SSH library vulnerable to Man-in-the-Middle attacks
(updated )
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.
