This dependency was removed in 2af6db672e, but
was re-introduced in commit 2fab240f21.
Now that golang.org/x/tools also stopped using this dependency, removing
this use will remove the package from our dependency tree.

This fixes the same CVE as go1.21.3 and go1.20.10;
- net/http: rapid stream resets can cause excessive work
A malicious HTTP/2 client which rapidly creates requests and
immediately resets them can cause excessive server resource consumption.
While the total number of requests is bounded to the
http2.Server.MaxConcurrentStreams setting, resetting an in-progress
request allows the attacker to create a new request while the existing
one is still executing.
HTTP/2 servers now bound the number of simultaneously executing
handler goroutines to the stream concurrency limit. New requests
arriving when at the limit (which can only happen after the client
has reset an existing, in-flight request) will be queued until a
handler exits. If the request queue grows too large, the server
will terminate the connection.
This issue is also fixed in golang.org/x/net/http2 v0.17.0,
for users manually configuring HTTP/2.
The default stream concurrency limit is 250 streams (requests)
per HTTP/2 connection. This value may be adjusted using the
golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams
setting and the ConfigureServer function.
This is CVE-2023-39325 and Go issue https://go.dev/issue/63417.
This is also tracked by CVE-2023-44487.

golang.org/x/net contains a fix for CVE-2022-41717, which was addressed
in stdlib in go1.19.4 and go1.18.9;
> net/http: limit canonical header cache by bytes, not entries
>
> An attacker can cause excessive memory growth in a Go server accepting
> HTTP/2 requests.
>
> HTTP/2 server connections contain a cache of HTTP header keys sent by
> the client. While the total number of entries in this cache is capped,
> an attacker sending very large keys can cause the server to allocate
> approximately 64 MiB per open connection.
>
> This issue is also fixed in golang.org/x/net/http2 v0.4.0,
> for users manually configuring HTTP/2.

Add a common NRI 'service' plugin. It takes care of relaying
requests and respones to and from NRI (external NRI plugins)
and the high-level containerd namespace-independent logic of
applying NRI container adjustments and updates to actual CRI
and other containers.
The namespace-dependent details of the necessary container
manipulation operations are to be implemented by namespace-
specific adaptations. This NRI plugin defines the API which
such adaptations need to implement.

Some minor improvements, but biggest for here is ErrPipeListenerClosed
is no longer an errors.New where the string matches the text of the now
exported net.ErrClosed in the stdlib, but is just assigned to net.ErrClosed
directly. This should allow us to get rid of the string check for "use of closed
network connection" here now..

This version contains a fix for CVE-2022-27191 (not sure if it affects us).
From the golang mailing list:
Hello gophers,
Version v0.0.0-20220315160706-3147a52a75dd of golang.org/x/crypto/ssh implements
client authentication support for signature algorithms based on SHA-2 for use with
existing RSA keys.
Previously, a client would fail to authenticate with RSA keys to servers that
reject signature algorithms based on SHA-1. This includes OpenSSH 8.8 by default
and—starting today March 15, 2022 for recently uploaded keys.
We are providing this announcement as the error (“ssh: unable to authenticate”)
might otherwise be difficult to troubleshoot.
Version v0.0.0-20220314234659-1baeb1ce4c0b (included in the version above) also
fixes a potential security issue where an attacker could cause a crash in a
golang.org/x/crypto/ssh server under these conditions:
- The server has been configured by passing a Signer to ServerConfig.AddHostKey.
- The Signer passed to AddHostKey does not also implement AlgorithmSigner.
- The Signer passed to AddHostKey does return a key of type “ssh-rsa” from its PublicKey method.
Servers that only use Signer implementations provided by the ssh package are
unaffected. This is CVE-2022-27191.
Alla prossima,
Filippo for the Go Security team

In linux 5.14 and hopefully some backports, core scheduling allows processes to
be co scheduled within the same domain on SMT enabled systems.
The containerd impl sets the core sched domain when launching a shim. This
allows a clean way for each shim(container/pod) to be in its own domain and any
additional containers, (v2 pods) be be launched with the same domain as well as
any exec'd process added to the container.
