Node.js: Node.js: Information disclosure via timing oracle in HMAC verification

A flaw was found in Node.js. The HMAC Hash-based Message Authentication Code verification process uses a comparison method that does not take a constant amount of time. This non-constant-time comparison can leak timing information, which, under specific conditions where precise timing measurement...
