go1.21.9 (released 2024-04-03) includes a security fix to the net/http
package, as well as bug fixes to the linker, and the go/types and
net/http packages. See the [Go 1.21.9 milestone](https://github.com/golang/go/issues?q=milestone%3AGo1.21.9+label%3ACherryPickApproved)
for more details.
These minor releases include 1 security fixes following the security policy:
- http2: close connections when receiving too many headers
Maintaining HPACK state requires that we parse and process all HEADERS
and CONTINUATION frames on a connection. When a request's headers exceed
MaxHeaderBytes, we don't allocate memory to store the excess headers but
we do parse them. This permits an attacker to cause an HTTP/2 endpoint
to read arbitrary amounts of header data, all associated with a request
which is going to be rejected. These headers can include Huffman-encoded
data which is significantly more expensive for the receiver to decode
than for an attacker to send.
Set a limit on the amount of excess header frames we will process before
closing a connection.

[security] Go 1.21.5 and Go 1.20.12 are released
Hello gophers,
We have just released Go versions 1.21.5 and 1.20.12, minor point releases.
These minor releases include 3 security fixes following the security policy:
- net/http: limit chunked data overhead
A malicious HTTP sender can use chunk extensions to cause a receiver
reading from a request or response body to read many more bytes from
the network than are in the body.
A malicious HTTP client can further exploit this to cause a server to
automatically read a large amount of data (up to about 1GiB) when a
handler fails to read the entire body of a request.
Chunk extensions are a little-used HTTP feature which permit including
additional metadata in a request or response body sent using the chunked
encoding. The net/http chunked encoding reader discards this metadata.
A sender can exploit this by inserting a large metadata segment with
each byte transferred. The chunk reader now produces an error if the
ratio of real body to encoded bytes grows too small.
Thanks to Bartek Nowotarski for reporting this issue.
This is CVE-2023-39326 and Go issue https://go.dev/issue/64433.
- cmd/go: go get may unexpectedly fallback to insecure git
Using go get to fetch a module with the ".git" suffix may unexpectedly
fallback to the insecure "git://" protocol if the module is unavailable
via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE
is not set for said module. This only affects users who are not using
the module proxy and are fetching modules directly (i.e. GOPROXY=off).
Thanks to David Leadbeater for reporting this issue.
This is CVE-2023-45285 and Go issue https://go.dev/issue/63845.
- path/filepath: retain trailing \ when cleaning paths like \\?\c:\
Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the
volume name in Windows paths starting with \\?\, resulting in
filepath.Clean(\\?\c:\) returning \\?\c: rather than \\?\c:\ (among
other effects). The previous behavior has been restored.

[security] Go 1.21.4 and Go 1.20.11 are released
Hello gophers,
We have just released Go versions 1.21.4 and 1.20.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- path/filepath: recognize `\??\` as a Root Local Device path prefix.
On Windows, a path beginning with `\??\` is a Root Local Device path equivalent
to a path beginning with `\\?\`. Paths with a `\??\` prefix may be used to
access arbitrary locations on the system. For example, the path `\??\c:\x`
is equivalent to the more common path c:\x.
The filepath package did not recognize paths with a `\??\` prefix as special.
Clean could convert a rooted path such as `\a\..\??\b` into
the root local device path `\??\b`. It will now convert this
path into `.\??\b`.
`IsAbs` did not report paths beginning with `\??\` as absolute.
It now does so.
VolumeName now reports the `\??\` prefix as a volume name.
`Join(`\`, `??`, `b`)` could convert a seemingly innocent
sequence of path elements into the root local device path
`\??\b`. It will now convert this to `\.\??\b`.
This is CVE-2023-45283 and https://go.dev/issue/63713.
- path/filepath: recognize device names with trailing spaces and superscripts
The `IsLocal` function did not correctly detect reserved names in some cases:
- reserved names followed by spaces, such as "COM1 ".
- "COM" or "LPT" followed by a superscript 1, 2, or 3.
`IsLocal` now correctly reports these names as non-local.
This is CVE-2023-45284 and https://go.dev/issue/63713.

[security] Go 1.21.3 and Go 1.20.10 are released
Hello gophers,
We have just released Go versions 1.21.3 and 1.20.10, minor point releases.
These minor releases include 1 security fixes following the security policy:
- 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.

[security] Go 1.21.2 and Go 1.20.9 are released
Hello gophers,
We have just released Go versions 1.21.2 and 1.20.9, minor point releases.
These minor releases include 1 security fixes following the security policy:
- cmd/go: line directives allows arbitrary execution during build
"//line" directives can be used to bypass the restrictions on "//go:cgo_"
directives, allowing blocked linker and compiler flags to be passed during
compliation. This can result in unexpected execution of arbitrary code when
running "go build". The line directive requires the absolute path of the file in
which the directive lives, which makes exploting this issue significantly more
complex.
This is CVE-2023-39323 and Go issue https://go.dev/issue/63211.

Unfortunately this also means that the GO_VERSION can no longer be set to
versions lower than 1.21.0 (without additional changes), because older
versions do NOT provide the `.0` version, and Go 1.21.0 and up, no longer
provides URLs _without_ the `.0` version.

These minor releases include 4 security fixes following the security policy:
- cmd/go: go.mod toolchain directive allows arbitrary execution
The go.mod toolchain directive, introduced in Go 1.21, could be leveraged to
execute scripts and binaries relative to the root of the module when the "go"
command was executed within the module. This applies to modules downloaded using
the "go" command from the module proxy, as well as modules downloaded directly
using VCS software.
Thanks to Juho Nurminen of Mattermost for reporting this issue.

- html/template: improper handling of HTML-like comments within script contexts
The html/template package did not properly handle HMTL-like "<!--" and "-->"
comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may
cause the template parser to improperly interpret the contents of <script>
contexts, causing actions to be improperly escaped. This could be leveraged to
perform an XSS attack.

of "<script", "<!--", and "</script" within JS literals in <script> contexts.
This may cause the template parser to improperly consider script contexts to be
terminated early, causing actions to be improperly escaped. This could be
