{"id":"CVE-2017-8932","details":"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.","aliases":["GO-2022-0187"],"modified":"2026-02-23T08:07:17.752309Z","published":"2017-07-06T16:29:00.420Z","related":["MGASA-2017-0195","SUSE-RU-2017:1965-1","openSUSE-SU-2017:1649-1","openSUSE-SU-2017:1650-1","openSUSE-SU-2024:10802-1","openSUSE-SU-2024:10803-1","openSUSE-SU-2024:10804-1","openSUSE-SU-2024:10805-1","openSUSE-SU-2024:10812-1"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LZH4T47ROLZ6YEZBDVXVS2KISTDMXAPS/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-updates/2017-06/msg00079.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-updates/2017-06/msg00080.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:1859"},{"type":"ADVISORY","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1455191"},{"type":"ADVISORY","url":"https://github.com/golang/go/commit/9294fa2749ffee7edbbb817a0ef9fe633136fa9c"},{"type":"ADVISORY","url":"https://github.com/golang/go/issues/20040"},{"type":"ADVISORY","url":"https://go-review.googlesource.com/c/41070/"},{"type":"ADVISORY","url":"https://groups.google.com/d/msg/golang-announce/B5ww0iFt1_Q/TgUFJV14BgAJ"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1455191"},{"type":"REPORT","url":"https://github.com/golang/go/commit/9294fa2749ffee7edbbb817a0ef9fe633136fa9c"},{"type":"FIX","url":"http://lists.opensuse.org/opensuse-updates/2017-06/msg00079.html"},{"type":"FIX","url":"http://lists.opensuse.org/opensuse-updates/2017-06/msg00080.html"},{"type":"FIX","url":"https://github.com/golang/go/commit/9294fa2749ffee7edbbb817a0ef9fe633136fa9c"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/golang/go","events":[{"introduced":"0"},{"fixed":"9294fa2749ffee7edbbb817a0ef9fe633136fa9c"}]}],"versions":["go1.3beta1","go1.3beta2","go1.4beta1","go1.5beta1","go1.5beta2","go1.5beta3","go1.6beta1","go1.6beta2","go1.7beta1","go1.7beta2","go1.7rc1","go1.7rc2","go1.7rc3","go1.7rc4","go1.8beta1","go1.8beta2","release.r56","weekly","weekly.2009-11-06","weekly.2009-11-10","weekly.2009-11-10.1","weekly.2009-11-12","weekly.2009-11-17","weekly.2009-12-07","weekly.2009-12-09","weekly.2009-12-22","weekly.2010-01-05","weekly.2010-01-13","weekly.2010-01-27","weekly.2010-02-04","weekly.2010-02-17","weekly.2010-02-23","weekly.2010-03-04","weekly.2010-03-15","weekly.2010-03-22","weekly.2010-03-30","weekly.2010-04-13","weekly.2010-04-27","weekly.2010-05-04","weekly.2010-05-27","weekly.2010-06-09","weekly.2010-06-21","weekly.2010-07-01","weekly.2010-07-14","weekly.2010-07-29","weekly.2010-08-04","weekly.2010-08-11","weekly.2010-08-25","weekly.2010-09-06","weekly.2010-09-15","weekly.2010-09-22","weekly.2010-09-29","weekly.2010-10-13","weekly.2010-10-13.1","weekly.2010-10-20","weekly.2010-10-27","weekly.2010-11-02","weekly.2010-11-10","weekly.2010-11-23","weekly.2010-12-02","weekly.2010-12-08","weekly.2010-12-15","weekly.2010-12-15.1","weekly.2010-12-22","weekly.2011-01-06","weekly.2011-01-12","weekly.2011-01-19","weekly.2011-01-20","weekly.2011-02-01","weekly.2011-02-01.1","weekly.2011-02-15","weekly.2011-02-24","weekly.2011-03-07","weekly.2011-03-07.1","weekly.2011-03-15","weekly.2011-03-28","weekly.2011-04-04","weekly.2011-04-13","weekly.2011-04-27","weekly.2011-05-22","weekly.2011-06-02","weekly.2011-06-09","weekly.2011-06-16","weekly.2011-06-23","weekly.2011-07-07","weekly.2011-07-19","weekly.2011-07-29","weekly.2011-08-10","weekly.2011-08-17","weekly.2011-09-01","weekly.2011-09-07","weekly.2011-09-16","weekly.2011-09-21","weekly.2011-10-06","weekly.2011-10-18","weekly.2011-10-25","weekly.2011-10-26","weekly.2011-11-01","weekly.2011-11-02","weekly.2011-11-08","weekly.2011-11-09","weekly.2011-11-18","weekly.2011-12-01","weekly.2011-12-02","weekly.2011-12-06","weekly.2011-12-14","weekly.2011-12-22","weekly.2012-01-15","weekly.2012-01-20","weekly.2012-01-27","weekly.2012-02-07","weekly.2012-02-14","weekly.2012-02-22","weekly.2012-03-04","weekly.2012-03-13","weekly.2012-03-22","weekly.2012-03-27"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-8932.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
