Subject: [PATCH] backport fix for go Host header check
|
||||
|
||||
Go 1.20.6 and 1.19.11 include a security check of the http Host header:
|
||||
|
||||
https://github.com/golang/go/issues/60374
|
||||
|
||||
docker-cli fails this check:
|
||||
|
||||
$ docker exec -it ctr bash
|
||||
http: invalid Host header
|
||||
|
||||
This is a backported patch to fix this issue.
|
||||
|
||||
Issue: https://github.com/moby/moby/issues/45935
|
||||
Upstream PR: https://github.com/moby/moby/pull/45942
|
||||
|
||||
The upstream PR has been merged and will be included in v24.0.5.

|
||||
For local communications (npipe://, unix://), the hostname is not used,
|
||||
but we need valid and meaningful hostname.
|
||||
|
||||
The current code used the socket path as hostname, which gets rejected by
|
||||
go1.20.6 and go1.19.11 because of a security fix for [CVE-2023-29406 ][1],
|
||||
which was implemented in https://go.dev/issue/60374.
|
||||
|
||||
Prior versions go Go would clean the host header, and strip slashes in the
|
||||
process, but go1.20.6 and go1.19.11 no longer do, and reject the host
|
||||
header.
