CVE-2017-1000097
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOn Darwin, user's trust preferences for root certificates were not honored. If the user had a root certificate loaded in their Keychain that was explicitly not trusted, a Go program would still verify a connection using that root certificate.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOn Darwin/macOS, Go's crypto/tls package did not respect user-defined trust settings in the macOS Keychain. When a root certificate was explicitly marked as untrusted by the user in their Keychain, Go programs would still use that certificate to verify TLS connections, bypassing user-level certificate trust preferences.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Go versionRun 'go version' in terminal and compare the version number to the affected ranges: < 1.6.4 or >= 1.7.0 to < 1.7.4Affected if The installed Go version falls within < 1.6.4 or >= 1.7.0 to < 1.7.4 on macOS
-
Confirm macOS/Darwin platformRun 'uname -s' and verify the output is 'Darwin', or check System Preferences > About for macOS versionAffected if The system is running macOS/Darwin; this vulnerability does not affect other platforms
-
Identify Go programs using TLS with default Keychain trustSearch Go codebase for uses of 'crypto/tls' package with default TLS configuration (Config rootCA field not set, or using tls.Config{} without custom RootCAs)Affected if The Go application uses crypto/tls without explicitly setting a custom CA bundle and relies on the system Keychain for certificate verification
-
Inspect Keychain for explicitly untrusted certificatesOpen Keychain Access app, select 'System Roots' or 'login' keychain, and look for certificates with a red X indicating 'Always Trust: Never' or explicitly untrusted statusAffected if There are certificates in the Keychain that the user has explicitly marked as untrusted, which Go would still accept for TLS verification
User is affected if running Go versions < 1.6.4 or >= 1.7.0 to < 1.7.4 on macOS with Go programs that use default TLS verification relying on the Keychain, and there are certificates explicitly marked as untrusted in the Keychain that should be rejected but would be accepted.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data1.6.41.7.4
Upgrade to Go version 1.8.4 or later (or Go 1.9+) which contains the fix. Alternatively, remove untrusted certificates from the Keychain or use custom TLS configurations with explicit CA bundles.
