Update Golang 1.12.16 (CVE-2020-0601, CVE-2020-7919) full diff: https://github.com/golang/go/compare/go1.12.15...go1.12.16 go1.12.16 (released 2020/01/28) includes two security fixes. One mitigates the CVE-2020-0601 certificate verification bypass on Windows. The other affects only 32-bit architectures. https://github.com/golang/go/issues?q=milestone%3AGo1.12.16+label%3ACherryPickApproved - X.509 certificate validation bypass on Windows 10 A Windows vulnerability allows attackers to spoof valid certificate chains when the system root store is in use. These releases include a mitigation for Go applications, but it’s strongly recommended that affected users install the Windows security update to protect their system. This issue is CVE-2020-0601 and Go issue golang.org/issue/36834. - Panic in crypto/x509 certificate parsing and golang.org/x/crypto/cryptobyte On 32-bit architectures, a malformed input to crypto/x509 or the ASN.1 parsing functions of golang.org/x/crypto/cryptobyte can lead to a panic. The malformed certificate can be delivered via a crypto/tls connection to a client, or to a server that accepts client certificates. net/http clients can be made to crash by an HTTPS server, while net/http servers that accept client certificates will recover the panic and are unaffected. Thanks to Project Wycheproof for providing the test cases that led to the discovery of this issue. The issue is CVE-2020-7919 and Go issue golang.org/issue/36837. This is also fixed in version v0.0.0-20200124225646-8b5121be2f68 of golang.org/x/crypto/cryptobyte.

Dockerfile: use GO_VERSION build-arg for overriding Go version This allows overriding the version of Go without making modifications in the source code, which can be useful to test against multiple versions. For example: make GO_VERSION=1.13beta1 -f docker.Makefile binary Signed-off-by: Sebastiaan van Stijn <github@gone.nl> 2019-07-18 05:13:45 -04:00

Do not patch Dockerfiles in CI When building the Dockerfiles for development, those images are mainly used to create a reproducible build-environment. The source code is bind-mounted into the image at runtime; there is no need to create an image with the actual source code, and copying the source code into the image would lead to a new image being created for each code-change (possibly leading up to many "dangling" images for previous code-changes). However, when building (and using) the development images in CI, bind-mounting is not an option, because the daemon is running remotely. To make this work, the circle-ci script patched the Dockerfiles when CI is run; adding a `COPY` to the respective Dockerfiles. Patching Dockerfiles is not really a "best practice" and, even though the source code does not and up in the image, the source would still be _sent_ to the daemon for each build (unless BuildKit is used). This patch updates the makefiles, circle-ci script, and Dockerfiles; - When building the Dockerfiles locally, pipe the Dockerfile through stdin. Doing so, prevents the build-context from being sent to the daemon. This speeds up the build, and doesn't fill up the Docker "temp" directory with content that's not used - Now that no content is sent, add the COPY instructions to the Dockerfiles, and remove the code in the circle-ci script to "live patch" the Dockerfiles.
