Debian: DSA-4380-1 Critical: Golang-1.8 Denial Of Service And Key Recovery

A vulnerability was discovered in the implementation of the P-521 and
P-384 elliptic curves, which could result in denial of service and in
some cases key recovery.

In addition this update fixes two vulnerabilities in "go get", which
could result in the execution of arbitrary shell commands.

For the stable distribution (stretch), these problems have been fixed in
version 1.8.1-1+deb9u1.

We recommend that you upgrade your golang-1.8 packages.

For the detailed security status of golang-1.8 please refer to
