CVE-2021-34558

CVE-2021-34558 affects the Go crypto/tls implementation. In Go up to 1.16.5, the certificate public-key type is not properly validated for RSA-based key exchanges, allowing a TLS server to trigger a panic in the client. Several connected advisories link this to Go’s TLS handling and note remediat...

go -- crypto/tls: clients can panic when provided a certificate of the wrong type for the negotiated parameters

The Go project reports: crypto/tls clients can panic when provided a certificate of the wrong type for the negotiated parameters. net/http clients performing HTTPS requests are also affected. The panic can be triggered by an attacker in a privileged network position without access to the server...

New Crypto in Go 1.14

Go 1.14 is out and with it come a few nice updates to crypto/tls! Will this certificate work? Certificate selection in TLS1 is a mess. I was going to try and describe it here to make the point, but I kept getting it wrong and it was even too messy for something just meant to make the point that i...

So you want to expose Go on the Internet

I was asked to contribute a post to the excellent Gopher Academy advent series. I took the occasion to write down what I learned deploying a Go service on the Cloudflare edge. The result is a catalogue of what you need to know before you drop NGINX from in front of your Go server. The net/http pa...
