A bug in the standard library ScalarMult implementation of curve P-256 for
amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes
incorrect results to be generated for specific input points. An adaptive
attack can be mounted to progressively extract the scalar input to
ScalarMult by submitting crafted points and observing failures to the
derive correct output. This leads to a full key recovery attack against
static ECDH, as used in popular JWT libraries.
