Subject: [PATCH 1/4] [release-branch.go1.20] 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.
|
||||
|
||||
For #60374
|
||||
Fixes #61076
|
||||
For CVE-2023-29406
