Update Golang 1.12.16 (CVE-2020-0601, CVE-2020-7919)
full diff: golang/go@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
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.
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

This is also fixed in version v0.0.0-20200124225646-8b5121be2f68 of golang.org/x/crypto/cryptobyte.
