{"id":"GHSA-cjjc-xp8v-855w","summary":"Helm uses crypto package vulnerable to panic from malformed X.509 certificate","details":"The Helm core maintainers have identified a high severity security vulnerability in Go's `crypto` package affecting all versions prior to Helm 2.16.8 and Helm 3.1.0.\n\nThanks to @ravin9249 for identifying the vulnerability.\n\n### Impact\n\nGo before 1.12.16 and 1.13.x before 1.13.7 (and the `crypto/cryptobyte` package before 0.0.0-20200124225646-8b5121be2f68 for Go) allows attacks on clients resulting in a panic via a malformed X.509 certificate. This may allow a remote attacker to cause a denial of service.\n\n### Patches\n\nA patch to compile Helm against Go 1.14.4 has been provided for Helm 2 and is available in Helm 2.16.8. Helm 3.1.0 and newer are compiled against Go 1.13.7+.\n\n### Workarounds\n\nNo workaround is available. Users are urged to upgrade.\n\n### References\n\n- https://nvd.nist.gov/vuln/detail/CVE-2020-7919\n- https://github.com/helm/helm/pull/8288\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in [the Helm repository](https://github.com/helm/helm/issues)\n* For security-specific issues, email us at \u003ccncf-helm-security@lists.cncf.io\u003e","aliases":["BIT-golang-2020-7919","CVE-2020-7919","GO-2022-0229"],"modified":"2026-07-17T21:15:04.616509698Z","published":"2021-06-23T18:02:39Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-06-18T22:07:33Z","nvd_published_at":"2020-03-16T21:15:00Z","cwe_ids":["CWE-295"]},"references":[{"type":"WEB","url":"https://github.com/helm/helm/security/advisories/GHSA-cjjc-xp8v-855w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-7919"},{"type":"PACKAGE","url":"https://github.com/helm/helm"},{"type":"WEB","url":"https://go.dev/cl/216677"},{"type":"WEB","url":"https://go.dev/cl/216680"},{"type":"WEB","url":"https://go.dev/issue/36837"},{"type":"WEB","url":"https://go.googlesource.com/go/+/b13ce14c4a6aa59b7b041ad2b6eed2d23e15b574"},{"type":"WEB","url":"https://groups.google.com/forum/#!forum/golang-announce"},{"type":"WEB","url":"https://groups.google.com/forum/#!topic/golang-announce/-sdUB4VEQkA"},{"type":"WEB","url":"https://groups.google.com/forum/#!topic/golang-announce/Hsw4mHYc470"},{"type":"WEB","url":"https://groups.google.com/g/golang-announce/c/Hsw4mHYc470"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/S43VLYRURELDWX4D5RFOYBNFGO6CGBBC"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2022-0229"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20200327-0001"},{"type":"WEB","url":"https://www.debian.org/security/2021/dsa-4848"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"}],"affected":[{"package":{"name":"github.com/helm/helm","ecosystem":"Go","purl":"pkg:golang/github.com/helm/helm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0"},{"fixed":"2.16.8"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/06/GHSA-cjjc-xp8v-855w/GHSA-cjjc-xp8v-855w.json"}},{"package":{"name":"helm.sh/helm/v3","ecosystem":"Go","purl":"pkg:golang/helm.sh/helm/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.1.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/06/GHSA-cjjc-xp8v-855w/GHSA-cjjc-xp8v-855w.json"}},{"package":{"name":"golang.org/x/crypto","ecosystem":"Go","purl":"pkg:golang/golang.org/x/crypto"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20200124225646-8b5121be2f68"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/06/GHSA-cjjc-xp8v-855w/GHSA-cjjc-xp8v-855w.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
