> Hello gophers,
>
> Version v0.17.0 of golang.org/x/crypto fixes a protocol weakness in the
> golang.org/x/crypto/ssh package that allowed a MITM attacker to compromise
> the integrity of the secure channel before it was established, allowing
> them to prevent transmission of a number of messages immediately after
> the secure channel was established without either side being aware.
>
> The impact of this attack is relatively limited, as it does not compromise
> confidentiality of the channel. Notably this attack would allow an attacker
> to prevent the transmission of the SSH2_MSG_EXT_INFO message, disabling a
> handful of newer security features.
>
> This protocol weakness was also fixed in OpenSSH 9.6.
>
> Thanks to Fabian Bäumer, Marcus Brinkmann, and Jörg Schwenk from Ruhr
> University Bochum for reporting this issue.

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.

This sets BuildKit version from the build information embedded
in running binary so we are aligned with the expected vendoring.
We iterate over all dependencies and find the BuildKit one
and set the right version. We also check if the module is
replaced and use it this case.
There is also additional checks if a pseudo version is
detected. See comments in code for more info.

...for limiting concurrent external DNS requests with
"golang.org/x/sync/semaphore".Weighted. Replace the ad-hoc rate limiter
for when the concurrency limit is hit (which contains a data-race bug)
with "golang.org/x/time/rate".Sometimes.
Immediately retrying with the next server if the concurrency limit has
been hit just further compounds the problem. Wait on the semaphore and
refuse the query if it could not be acquired in a reasonable amount of
time.

This addresses the same CVE as is patched in go1.19.6. From that announcement:

This is a pragmatic but impure choice, in order to better support the
default tools available on Windows Server, and reduce user confusion due
to otherwise inscrutable-to-the-uninitiated errors like the following:
> invalid character 'þ' looking for beginning of value
> invalid character 'ÿ' looking for beginning of value
While meaningful to those who are familiar with and are equipped to
diagnose encoding issues, these characters will be hidden when the file
is edited with a BOM-aware text editor, and further confuse the user.

The singleflight function was capturing the context.Context of the first
caller that invoked the `singleflight.Do`. This could cause all
concurrent calls to be cancelled when the first request is cancelled.
singleflight calls were also moved from the ImageService to Daemon, to
avoid having to implement this logic in both graphdriver and containerd
based image services.
