cmd/go: golang: cmd/go: Toolchain checksum verification bypass via crafted project configuration

A flaw was found in the Go toolchain cmd/go. When a user works inside a malicious Go project that forges a golang.org/toolchain go.sum entry and uses an untrusted Go module proxy, cmd/go can skip the canonical checksum database check for toolchain downloads. A tampered toolchain may then be...
