CVE-2020-13822
Description
The Elliptic for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature.
Statement
In both OpenShift Container Platform (OCP) and OpenShift ServiceMesh (OSSM), the grafana and prometheus containers don't use the vulnerable elliptic library for authentication (OpenShift OAuth is used) or traffic communications (OpenShift route is used). Therefore the impact for OCP and OSSM is Low.
Red Hat Quay includes nodejs-elliptic as a dependency of webpack. That dependency is only used at development time, not runtime. Therefore this vulnerability is rated low for Red Hat Quay.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
