On Windows, configuring a named pipe server with pipe_mode will force ServerOptions::reject_remote_clients as false.

This drops any intended explicit configuration for the reject_remote_clients that may have been set as true previously.

The default setting of reject_remote_clients is normally true meaning the default is also overridden as false.

Workarounds

Ensure that pipe_mode is set first after initializing a ServerOptions. For example:

let mut opts = ServerOptions::new();
opts.pipe_mode(PipeMode::Message);
opts.reject_remote_clients(true);

Exposure of temporary credentials in logs in Apache Arrow Rust Object Store, version 0.10.1 and earlier on all platforms using AWS WebIdentityTokens.

On certain error conditions, the logs may contain the OIDC token passed to AssumeRoleWithWebIdentity. This allows someone with access to the logs to impersonate that identity, including performing their own calls to AssumeRoleWithWebIdentity, until the OIDC token expires. Typically OIDC tokens are valid for up to an hour, although this will vary depending on the issuer.

Users are recommended to use a different AWS authentication mechanism, disable logging or upgrade to version 0.10.2, which fixes this issue.

Details

When using AWS WebIdentityTokens with the object_store crate, in the event of a failure and automatic retry, the underlying reqwest error, including the full URL with the credentials, potentially in the parameters, is written to the logs.
