Fixes the following security issues:
- cmd/go: packages using cgo can cause arbitrary code execution at build time
The go command may execute arbitrary code at build time when cgo is in use
on Windows. This may occur when running “go get”, or any other command
that builds code. Only users who build untrusted code (and don’t execute
it) are affected.
In addition to Windows users, this can also affect Unix users who have “.”
listed explicitly in their PATH and are running “go get” or build commands
outside of a module or with module mode disabled.
Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this issue.
This issue is CVE-2021-3115 and Go issue golang.org/issue/43783.
- crypto/elliptic: incorrect operations on the P-224 curve
The P224() Curve implementation can in rare circumstances generate
incorrect outputs, including returning invalid points from ScalarMult.
The crypto/x509 and golang.org/x/crypto/ocsp (but not crypto/tls) packages
support P-224 ECDSA keys, but they are not supported by publicly trusted
certificate authorities. No other standard library or golang.org/x/crypto
package supports or uses the P-224 curve.
The incorrect output was found by the elliptic-curve-differential-fuzzer
project running on OSS-Fuzz and reported by Philippe Antoine (Catena cyber).
This issue is CVE-2021-3114 and Go issue golang.org/issue/43786.

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 http://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 Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
