go1.21.5 (released 2023-12-05) includes security fixes to the go command,
and the net/http and path/filepath packages, as well as bug fixes to the
compiler, the go command, the runtime, and the crypto/rand, net, os, and
syscall packages. See the Go 1.21.5 milestone on our issue tracker for

[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.
This is an update to CVE-2023-45283 and Go issue https://go.dev/issue/64028.

update to go1.21.4
go1.21.4 (released 2023-11-07) includes security fixes to the path/filepath package, as well as bug fixes to the linker, the runtime, the compiler, and the go/types, net/http, and runtime/cgo packages. See the Go 1.21.4 milestone on our issue tracker for details:

[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.

"By default" implies that this is something which could be
disabled for an individual `docker exec` call. This doesn't seem
to be the case, so removing the "by default" part would make
these docs clearer to me.

- updates fc6976db45
- updates 74bace156c
Commit fc6976db45 introduced support for the
`bind-recursive` option on `--mount`, and deprecated the `bind-nonrecursive`
option. Unlike `bind-nonrecursive` boolean, the `bind-recursive` option
accepts a string value with multiple options.
For convenience, the `bind-recursive` option also was made to accept boolean
values (true/false, 1/0). However, as the option works as the _reverse_ of
`bind-nonrecursive` (`bind-nonrecursive=true` === `bind-recursive=false`),
the new option won't be a "drop-in" replacement, and having more options
to choose from may only be adding more complexity / cognitive overload.
This patch removes support for boolean values; if we see a need to add
support for boolean values in future, it would be trivial to add back this
functionality.

The linter is correct; given that these functions do not allow for an error
to be returned, we panic. Alternatively, we could return the error string
as output, or add a `//nolint:errchkjson` comment.
