build(deps): bump github.com/hashicorp/vault/api/auth/gcp from 0.2.0 to 0.5.0

[dependabot]

Bumps github.com/hashicorp/vault/api/auth/gcp from 0.2.0 to 0.5.0.

Changelog

Sourced from github.com/hashicorp/vault/api/auth/gcp's changelog.

0.5.0 (February 10, 2016)

SECURITY:

• Previous versions of Vault could allow a malicious user to hijack the rekey operation by canceling an operation in progress and starting a new one. The practical application of this is very small. If the user was an unseal key owner, they could attempt to do this in order to either receive unencrypted reseal keys or to replace the PGP keys used for encryption with ones under their control. However, since this would invalidate any rekey progress, they would need other unseal key holders to resubmit, which would be rather suspicious during this manual operation if they were not also the original initiator of the rekey attempt. If the user was not an unseal key holder, there is no benefit to be gained; the only outcome that could be attempted would be a denial of service against a legitimate rekey operation by sending cancel requests over and over. Thanks to Josh Snyder for the report!

DEPRECATIONS/CHANGES:

• s3 physical backend: Environment variables are now preferred over configuration values. This makes it behave similar to the rest of Vault, which, in increasing order of preference, uses values from the configuration file, environment variables, and CLI flags. GH-871
• etcd physical backend: sync functionality is now supported and turned on by default. This can be disabled. GH-921
• transit: If a client attempts to encrypt a value with a key that does not yet exist, what happens now depends on the capabilities set in the client's ACL policies. If the client has create (or create and update) capability, the key will upsert as in the past. If the client has update capability, they will receive an error. GH-1012
• token-renew CLI command: If the token given for renewal is the same as the client token, the renew-self endpoint will be used in the API. Given that the default policy (by default) allows all clients access to the renew-self endpoint, this makes it much more likely that the intended operation will be successful. GH-894
• Token lookup: the ttl value in the response now reflects the actual remaining TTL rather than the original TTL specified when the token was created; this value is now located in creation_ttl GH-986
• Vault no longer uses grace periods on leases or token TTLs. Uncertainty about the length grace period for any given backend could cause confusion and uncertainty. GH-1002
• rekey: Rekey now requires a nonce to be supplied with key shares. This nonce is generated at the start of a rekey attempt and is unique for that attempt.
• status: The exit code for the status CLI command is now 2 for an uninitialized Vault instead of 1. 1 is returned for errors. This better matches the rest of the CLI.
