Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
A vulnerability in Go was discovered which does not validate the import path of remote repositories.
Remote attackers, by enticing a user to import from a crafted website, could execute arbitrary commands.
There is no known workaround at this time.
All Go users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/go-1.10.1"
