{"cve":"CVE-2017-8932","nvd":{"published":"2017-07-06T16:29:00.420","modified":"2026-06-17T01:27:13.483","status":"Modified","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9},"cwes":["CWE-682"],"references":["http://lists.opensuse.org/opensuse-updates/2017-06/msg00079.html","http://lists.opensuse.org/opensuse-updates/2017-06/msg00080.html","https://access.redhat.com/errata/RHSA-2017:1859","https://bugzilla.redhat.com/show_bug.cgi?id=1455191","https://github.com/golang/go/commit/9294fa2749ffee7edbbb817a0ef9fe633136fa9c"],"products":["fedoraproject:fedora","golang:go","novell:suse_package_hub_for_suse_linux_enterprise","opensuse:leap"],"source":"nvd","synced_at":"2026-10-19T20:43:44.556243339+00:00"},"epss":{"cve":"CVE-2017-8932","score":0.02225,"percentile":0.82712,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GO-2022-0187","url":"https://osv.dev/vulnerability/GO-2022-0187","summary":"Incorrect computation for P-256 curves in crypto/elliptic","modified":"2024-05-20T16:03:47Z","packages":[{"ecosystem":"Go","name":"stdlib","purl":"pkg:golang/stdlib","ranges":[">=1.6.0-0 <1.7.6",">=1.8.0-0 <1.8.2"],"fixed":["1.7.6","1.8.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
