    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. Thanks to @ravin9249 for identifying the vulnerability. ### Impact Go 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. ### Patches A 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+. ### Workarounds No workaround is available. Users are urged to upgrade. ### References - https://nvd.nist.gov/vuln/detail/CVE-2020-7919 - https://github.com/helm/helm/pull/8288 ### For more information If you have any questions or comments about this advisory: * Open an issue in [the Helm repository](https://github.com/helm/helm/issues) * For security-specific issues, email us at <[email protected]>
