From the mailing list:
We have just released Go versions 1.19.1 and 1.18.6, minor point releases.
These minor releases include 2 security fixes following the security policy:
- net/http: handle server errors after sending GOAWAY
A closing HTTP/2 server connection could hang forever waiting for a clean
shutdown that was preempted by a subsequent fatal error. This failure mode
could be exploited to cause a denial of service.
Thanks to Bahruz Jabiyev, Tommaso Innocenti, Anthony Gavazzi, Steven Sprecher,
and Kaan Onarlioglu for reporting this.
This is CVE-2022-27664 and Go issue https://go.dev/issue/54658.
- net/url: JoinPath does not strip relative path components in all circumstances
JoinPath and URL.JoinPath would not remove `../` path components appended to a
relative path. For example, `JoinPath("https://go.dev", "../go")` returned the
URL `https://go.dev/../go`, despite the JoinPath documentation stating that
`../` path elements are cleaned from the result.
Thanks to q0jt for reporting this issue.
This is CVE-2022-32190 and Go issue https://go.dev/issue/54385.
Release notes:
go1.18.6 (released 2022-09-06) includes security fixes to the net/http package,
as well as bug fixes to the compiler, the go command, the pprof command, the
runtime, and the crypto/tls, encoding/xml, and net packages. See the Go 1.18.6

We have just released Go versions 1.18.4 and 1.17.12, minor point releases. These
minor releases include 9 security fixes following the security policy:
- net/http: improper sanitization of Transfer-Encoding header
The HTTP/1 client accepted some invalid Transfer-Encoding headers as indicating
a "chunked" encoding. This could potentially allow for request smuggling, but
only if combined with an intermediate server that also improperly failed to
reject the header as invalid.
This is CVE-2022-1705 and https://go.dev/issue/53188.
- When `httputil.ReverseProxy.ServeHTTP` was called with a `Request.Header` map
containing a nil value for the X-Forwarded-For header, ReverseProxy would set
the client IP as the value of the X-Forwarded-For header, contrary to its
documentation. In the more usual case where a Director function set the
X-Forwarded-For header value to nil, ReverseProxy would leave the header
unmodified as expected.
This is https://go.dev/issue/53423 and CVE-2022-32148.
Thanks to Christian Mehlmauer for reporting this issue.
- compress/gzip: stack exhaustion in Reader.Read
Calling Reader.Read on an archive containing a large number of concatenated
0-length compressed files can cause a panic due to stack exhaustion.
This is CVE-2022-30631 and Go issue https://go.dev/issue/53168.
- encoding/xml: stack exhaustion in Unmarshal
Calling Unmarshal on a XML document into a Go struct which has a nested field
that uses the any field tag can cause a panic due to stack exhaustion.
This is CVE-2022-30633 and Go issue https://go.dev/issue/53611.
- encoding/xml: stack exhaustion in Decoder.Skip
Calling Decoder.Skip when parsing a deeply nested XML document can cause a
panic due to stack exhaustion. The Go Security team discovered this issue, and
it was independently reported by Juho Nurminen of Mattermost.
This is CVE-2022-28131 and Go issue https://go.dev/issue/53614.
- encoding/gob: stack exhaustion in Decoder.Decode
Calling Decoder.Decode on a message which contains deeply nested structures
can cause a panic due to stack exhaustion.
This is CVE-2022-30635 and Go issue https://go.dev/issue/53615.

Hello gophers,
We have just released Go versions 1.18.3 and 1.17.11, minor point releases.
These minor releases include 4 security fixes following the security policy:
- crypto/rand: rand.Read hangs with extremely large buffers
On Windows, rand.Read will hang indefinitely if passed a buffer larger than
1 << 32 - 1 bytes.

ticket_age_add. This allows an attacker that can observe TLS handshakes to
correlate successive connections by comparing ticket ages during session
resumption.

- `os/exec`: empty `Cmd.Path` can result in running unintended binary on Windows
If, on Windows, `Cmd.Run`, `cmd.Start`, `cmd.Output`, or `cmd.CombinedOutput`
are executed when Cmd.Path is unset and, in the working directory, there are
binaries named either "..com" or "..exe", they will be executed.

This makes some minor improvments to the dev container:
- add `nano` as an alternative to `vi` to help beginning contributors, or people
that don't remember how to quit `vi` ;-)
- add `jq` as it's often handy to have available to debug JSON output.
- set a custom prompt to make it clearer that the user is in a container
- add a short MOTD that shows that the user is in a container, and a pointer
to 'make help' (we can add more help/instructions to this MOTD in future).

worth noting that Go's native "embed" does not compress files. We could compress
these files as part of a build / validate step (which would add some complexity
when updating these files) if this is a concern, but not sure if the additional

CVE-2020-0601 certificate verification bypass on Windows. The other affects only
32-bit architectures.
https://github.com/golang/go/issues?q=milestone%3AGo1.12.16+label%3ACherryPickApproved
- X.509 certificate validation bypass on Windows 10
A Windows vulnerability allows attackers to spoof valid certificate chains when
the system root store is in use. These releases include a mitigation for Go
applications, but it’s strongly recommended that affected users install the
Windows security update to protect their system.
This issue is CVE-2020-0601 and Go issue golang.org/issue/36834.
- Panic in crypto/x509 certificate parsing and golang.org/x/crypto/cryptobyte
On 32-bit architectures, a malformed input to crypto/x509 or the ASN.1 parsing
functions of golang.org/x/crypto/cryptobyte can lead to a panic.
The malformed certificate can be delivered via a crypto/tls connection to a
client, or to a server that accepts client certificates. net/http clients can
be made to crash by an HTTPS server, while net/http servers that accept client
certificates will recover the panic and are unaffected.
Thanks to Project Wycheproof for providing the test cases that led to the
discovery of this issue. The issue is CVE-2020-7919 and Go issue golang.org/issue/36837.
This is also fixed in version v0.0.0-20200124225646-8b5121be2f68 of golang.org/x/crypto/cryptobyte.

[security] Go 1.13.2 and Go 1.12.11 are released
Hi gophers,
We have just released Go 1.13.2 and Go 1.12.11 to address a recently reported
security issue. We recommend that all affected users update to one of these
releases (if you're not sure which, choose Go 1.13.2).
Invalid DSA public keys can cause a panic in dsa.Verify. In particular, using
crypto/x509.Verify on a crafted X.509 certificate chain can lead to a panic,
even if the certificates don't chain to a trusted root. The chain can be
delivered via a crypto/tls connection to a client, or to a server that accepts
and verifies client certificates. net/http clients can be made to crash by an
HTTPS server, while net/http servers that accept client certificates will
recover the panic and are unaffected.
Moreover, an application might crash invoking
crypto/x509.(*CertificateRequest).CheckSignature on an X.509 certificate
request, parsing a golang.org/x/crypto/openpgp Entity, or during a
golang.org/x/crypto/otr conversation. Finally, a golang.org/x/crypto/ssh client
can panic due to a malformed host key, while a server could panic if either
PublicKeyCallback accepts a malformed public key, or if IsUserAuthority accepts
a certificate with a malformed public key.
The issue is CVE-2019-17596 and Go issue golang.org/issue/34960.
Thanks to Daniel Mandragona for discovering and reporting this issue. We'd also
like to thank regilero for a previous disclosure of CVE-2019-16276.

Hi gophers,
We have just released Go 1.13.1 and Go 1.12.10 to address a recently reported security issue. We recommend that all affected users update to one of these releases (if you're not sure which, choose Go 1.13.1).
net/http (through net/textproto) used to accept and normalize invalid HTTP/1.1 headers with a space before the colon, in violation of RFC 7230. If a Go server is used behind an uncommon reverse proxy that accepts and forwards but doesn't normalize such invalid headers, the reverse proxy and the server can interpret the headers differently. This can lead to filter bypasses or request smuggling, the latter if requests from separate clients are multiplexed onto the same upstream connection by the proxy. Such invalid headers are now rejected by Go servers, and passed without normalization to Go client applications.
The issue is CVE-2019-16276 and Go issue golang.org/issue/34540.

```
net/textproto: don't normalize headers with spaces before the colon
RFC 7230 is clear about headers with a space before the colon, like
X-Answer : 42
being invalid, but we've been accepting and normalizing them for compatibility
purposes since CL 5690059 in 2012.
On the client side, this is harmless and indeed most browsers behave the same
to this day. On the server side, this becomes a security issue when the
behavior doesn't match that of a reverse proxy sitting in front of the server.
For example, if a WAF accepts them without normalizing them, it might be
possible to bypass its filters, because the Go server would interpret the
header differently. Worse, if the reverse proxy coalesces requests onto a
single HTTP/1.1 connection to a Go server, the understanding of the request
boundaries can get out of sync between them, allowing an attacker to tack an
arbitrary method and path onto a request by other clients, including
authentication headers unknown to the attacker.
This was recently presented at multiple security conferences:
https://portswigger.net/blog/http-desync-attacks-request-smuggling-reborn
net/http servers already reject header keys with invalid characters.
Simply stop normalizing extra spaces in net/textproto, let it return them
unchanged like it does for other invalid headers, and let net/http enforce
RFC 7230, which is HTTP specific. This loses us normalization on the client
side, but there's no right answer on the client side anyway, and hiding the
issue sounds worse than letting the application decide.

- net/http: Denial of Service vulnerabilities in the HTTP/2 implementation
net/http and golang.org/x/net/http2 servers that accept direct connections from untrusted
clients could be remotely made to allocate an unlimited amount of memory, until the program
crashes. Servers will now close connections if the send queue accumulates too many control
messages.
The issues are CVE-2019-9512 and CVE-2019-9514, and Go issue golang.org/issue/33606.
Thanks to Jonathan Looney from Netflix for discovering and reporting these issues.
This is also fixed in version v0.0.0-20190813141303-74dc4d7220e7 of golang.org/x/net/http2.
net/url: parsing validation issue
- url.Parse would accept URLs with malformed hosts, such that the Host field could have arbitrary
suffixes that would appear in neither Hostname() nor Port(), allowing authorization bypasses
in certain applications. Note that URLs with invalid, not numeric ports will now return an error
from url.Parse.
The issue is CVE-2019-14809 and Go issue golang.org/issue/29098.

This patch switches the shellcheck image to use the official image
from Docker Hub.
Note that this does not yet update shellcheck to the latest version (v0.5.x);
Shellcheck v0.4.7 added some new checks, which makes CI currently fail, so will
be done in a follow-up PR. Instead, the v0.4.6 version is used in this PR, which
is closest to the same version as was installed in the image before this change;

When building the Dockerfiles for development, those images are mainly used to
create a reproducible build-environment. The source code is bind-mounted into
the image at runtime; there is no need to create an image with the actual
source code, and copying the source code into the image would lead to a new
image being created for each code-change (possibly leading up to many "dangling"
images for previous code-changes).
However, when building (and using) the development images in CI, bind-mounting
is not an option, because the daemon is running remotely.
To make this work, the circle-ci script patched the Dockerfiles when CI is run;
adding a `COPY` to the respective Dockerfiles.
Patching Dockerfiles is not really a "best practice" and, even though the source
code does not and up in the image, the source would still be _sent_ to the daemon
for each build (unless BuildKit is used).
This patch updates the makefiles, circle-ci script, and Dockerfiles;
- When building the Dockerfiles locally, pipe the Dockerfile through stdin.
Doing so, prevents the build-context from being sent to the daemon. This speeds
up the build, and doesn't fill up the Docker "temp" directory with content that's
not used
- Now that no content is sent, add the COPY instructions to the Dockerfiles, and
remove the code in the circle-ci script to "live patch" the Dockerfiles.
