CVE-2020-13822 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:20.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream node-elliptic package and not the node-elliptic package as distributed by Ubuntu.
The Elliptic package 6.5.2 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.
