Fixes the following vulnerabilities:
- CVE-2025-61728: 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.
- CVE-2025-61726: 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.
- CVE-2025-68121: 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.
- CVE-2025-61731: 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.
- CVE-2025-61730: 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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
