vulnerability from the CVE link(s) in the References section.

Go Toolset provides the Go programming language tools and libraries.
Go is alternatively known as golang.

Security Fix(es) :

* golang: HTTP/1.1 headers with a space before the colon leads to
filter bypass or request smuggling (CVE-2019-16276)

* golang: invalid public key causes panic in dsa.Verify
(CVE-2019-17596)
