[security] Go 1.20.6 and Go 1.19.11 are released

[anno...@golang.org]

Hello gophers,

We have just released Go versions 1.20.6 and 1.19.11, minor point releases.

These minor releases include 1 security fixes following the security policy:

• net/http: insufficient sanitization of Host header

  The HTTP/1 client did not fully validate the contents of the Host header. A maliciously crafted Host header could inject additional headers or entire requests. The HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value.

  Thanks to Bartek Nowotarski for reporting this issue.

  Includes security fixes for CVE-2023-29406 and Go issue https://go.dev/issue/60374

To compile from source using a Git clone, update to the release with
git checkout go1.20.6 and build as usual.

Thanks to everyone who contributed to the releases.

Cheers,
Cherry and Joedian for the Go team
