+-	crypto/x509: non-compliant certificates can cause a panic in Verify on macOS in Go 1.18
+
+	Verifying certificate chains containing certificates which are not compliant with RFC 5280 causes Certificate.Verify to panic on macOS.
+
+	These chains can be delivered through TLS and can cause a crypto/tls or net/http client to crash.
+
+	Thanks to Tailscale for doing weird things and finding this.
+
+	This is CVE-2022-27536 and https://go.dev/issue/51759.

+
+You can download binary and source distributions from the Go website:

+To compile from source using a Git clone, update to the release with
+git checkout go1.18.1 and build as usual.
