EC2 token requests contain a signature that signs the entire request, including the access timestamp. While the signature is checked, the timestamp is not, and so these signed requests remain valid indefinitely, leaving the token API vulnerable to replay attacks. This change introduces a configurable TTL for signed token requests and ensures that the timestamp is actually validated against it. The check will work for either an AWS Signature v1/v2 'Timestamp' parameter[1] or the AWS Signature v4 'X-Aws-Date' header or parameter[2]. Although this technically adds a new feature and the default value of the feature changes behavior, this change is required to protect credential holders and therefore must be backported to all supported branches.
