+Subject: [PATCH] [release-branch.go1.19] net/http: validate Host header before
+ sending
+
+Verify that the Host header we send is valid.
+Avoids surprising behavior such as a Host of "go.dev\r\nX-Evil:oops"
+adding an X-Evil header to HTTP/1 requests.
+
+Add a test, skip the test for HTTP/2. HTTP/2 is not vulnerable to
+header injection in the way HTTP/1 is, but x/net/http2 doesn't validate
+the header and will go into a retry loop when the server rejects it.
+CL 506995 adds the necessary validation to x/net/http2.
+
+Updates #60374
+Fixes #61075
+For CVE-2023-29406
