- Summary
- cookie-signature Timing Attack
- Details
-
Affected versions of
cookie-signatureare vulnerable to timing attacks as a result of using a fail-early comparison instead of a constant-time comparison.Timing attacks remove the exponential increase in entropy gained from increased secret length, by providing per-character feedback on the correctness of a guess via miniscule timing differences.
Under favorable network conditions, an attacker can exploit this to guess the secret in no more than
charset*lengthguesses, instead ofcharset^lengthguesses required were the timing attack not present.Recommendation
Update to 1.0.4 or later.
