Ignore errors when trying to remove a CID-file that no longer exists;
also remove the path from the custom error as os.Remove already returns
a os.PathError, which includes the path.

Include the container-ID in the error message when failing to write
the ID to a file, so that the user can still find the ID of the container
that was created.

This releases includes 6 security fixes following the security policy:
- archive/zip: denial of service when parsing arbitrary ZIP archives
archive/zip used a super-linear file name indexing algorithm that is invoked the first time a file in an archive is opened. This can lead to a denial of service when consuming a maliciously constructed ZIP archive.
Thanks to Thanks to Jakub Ciolek for reporting this issue.
This is CVE-2025-61728 and Go issue https://go.dev/issue/77102.
- net/http: memory exhaustion in Request.ParseForm
When parsing a URL-encoded form net/http may allocate an unexpected amount of
memory when provided a large number of key-value pairs. This can result in a
denial of service due to memory exhaustion.

This is CVE-2025-61726 and Go issue https://go.dev/issue/77101.
- crypto/tls: Config.Clone copies automatically generated session ticket keys, session resumption does not account for the expiration of full certificate chain
The Config.Clone methods allows cloning a Config which has already been passed
to a TLS function, allowing it to be mutated and reused.
If Config.SessionTicketKey has not been set, and Config.SetSessionTicketKeys has
not been called, crypto/tls will generate random session ticket keys and
automatically rotate them. Config.Clone would copy these automatically generated
keys into the returned Config, meaning that the two Configs would share session
ticket keys, allowing sessions created using one Config could be used to resume
sessions with the other Config. This can allow clients to resume sessions even
though the Config may be configured such that they should not be able to do so.
Config.Clone no longer copies the automatically generated session ticket keys.
Config.Clone still copies keys which are explicitly provided, either by setting
Config.SessionTicketKey or by calling Config.SetSessionTicketKeys.
This issue was discoverd by the Go Security team while investigating another
issue reported by Coia Prant (github.com/rbqvq).
Additionally, on the server side only the expiration of the leaf certificate, if
one was provided during the initial handshake, was checked when considering if a
session could be resumed. This allowed sessions to be resumed if an intermediate
or root certificate in the chain had expired.
Session resumption now takes into account of the full chain when determining if
the session can be resumed.

This is CVE-2025-68121 and Go issue https://go.dev/issue/77113.
- cmd/go: bypass of flag sanitization can lead to arbitrary code execution
Usage of 'CgoPkgConfig' allowed execution of the pkg-config
binary with flags that are not explicitly safe-listed.
To prevent this behavior, compiler flags resulting from usage
of 'CgoPkgConfig' are sanitized prior to invoking pkg-config.
Thank you to RyotaK (https://ryotak.net) of GMO Flatt Security Inc.
for reporting this issue.
This is CVE-2025-61731 and go.dev/issue/77100.
- cmd/go: unexpected code execution when invoking toolchain
The Go toolchain supports multiple VCS which are used retrieving modules and
embedding build information into binaries.
On systems with Mercurial installed (hg) downloading modules (e.g. via go get or
go mod download) from non-standard sources (e.g. custom domains) can cause
unexpected code execution due to how external VCS commands are constructed.
On systems with Git installed, downloading and building modules with malicious
version strings could allow an attacker to write to arbitrary files on the
system the user has access to. This can only be triggered by explicitly
providing the malicious version strings to the toolchain, and does not affect
usage of @latest or bare module paths.
The toolchain now uses safer VCS options to prevent misinterpretation of
untrusted inputs. In addition, the toolchain now disallows module version
strings prefixed with a "-" or "/" character.
Thanks to splitline (@splitline) from DEVCORE Research Team for reporting this
issue.
This is CVE-2025-68119 and Go issue https://go.dev/issue/77099.
- crypto/tls: handshake messages may be processed at the incorrect encryption level
During the TLS 1.3 handshake if multiple messages are sent in records that span
encryption level boundaries (for instance the Client Hello and Encrypted
Extensions messages), the subsequent messages may be processed before the
encryption level changes. This can cause some minor information disclosure if a
network-local attacker can inject messages during the handshake.
Thanks to Coia Prant (github.com/rbqvq) for reporting this issue.
This is CVE-2025-61730 and Go issue https://go.dev/issue/76443

Before this change, the detach-keys were not validated, and the code either
fell back to the default sequence, or returned an obscure error if the
invalid sequence would produce an error on the daemon;
Before this patch:
docker run -it --rm --detach-keys=shift-a,b busybox
unable to upgrade to tcp, received 400
With this patch:
docker run -it --rm --detach-keys=shift-a,b busybox
invalid detach keys (shift-a,b): Unknown character: 'shift-a'
Note that the "unable to upgrade to tcp, received 400" error is still
something to be looked into; the client currently discards error messages
coming from the daemon.

Use a more generic "clientOptions" field to store options to apply
when constructing the API client, instead of a dedicated field for
user-agent.

Changed the environment variables section description from:
"The following list of environment variables are supported by the `docker` command line:"
To:
"The following environment variables control the behavior of the `docker` command-line client:"
This makes it clearer that these variables control Docker's behavior, and uses the more precise term "command-line client" instead of "command line".
