| summary: Insufficient sanitization of Host header in net/http |
| description: |- |
| The HTTP/1 client does not fully validate the contents of the Host header. A |
| maliciously crafted Host header can inject additional headers or entire |
| requests. |
| |
| With fix, the HTTP/1 client now refuses to send requests containing an invalid |
| Request.Host or Request.URL.Host value. |
