Bug Description

Affected versions:

Bionic - 1.0.0-0ubuntu4~18.04.6
Xenial - 1.0.0-0ubuntu4~16.04.4

IMDSv2 is a protocol that Amazon maintains to access instance metadata. IMDSv1 uses a request/respond method, whereas IMDSv2 uses a session-oriented method.

IMDSv2 is a more secure protocol and is recommended going forward.
