CVE-2017-8932 (opens in a new tab)How to fix?
There is no fixed version for Debian:9 golang-1.7.
NVD Description
Note: Versions mentioned in the description apply only to the upstream golang-1.7 package and not the golang-1.7 package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
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.
