JSON

A flaw was found in the Elliptic package for Node.js. ECDSA signatures encoded in BER format are improperly validated, allowing leading zeros to be added to the signature without invalidating it, resulting in confidentiality issues.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
