Description Laura Pardo 2018-02-16 22:42:02 UTC
A flaw was found in Go Lang. The "go get" implementation in Go 1.9.4, when the -insecure command-line option is used, does not validate the import path (get/vcs.go only checks for "://" anywhere in the string), which allows remote attackers to execute arbitrary OS commands via a crafted web site.

Comment 2 Joshua Padman 2018-02-19 00:53:33 UTC
golang was included in Red Hat OpenStack 8 & 9 operational tools only as a technical preview for customers, it was provided without support and is not intended to be deployed in production.
