## Vulnerabilities

* [Medium] CVE-2024-1544
11-
Potential ECDSA nonce side channel attack in versions of wolfSSL before 5.6.6 with wc_ecc_sign_hash calls. Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Analyzing the division through a control*flow revealing side-channel reveals a bias in the most significant bits of k. Depending on the curve this is either a negligible bias or a significant bias large enough to reconstruct k with lattice reduction methods. Thanks to Luca Wilke, Florian Sieck and Thomas Eisenbarth (University of Lübeck) for reporting the vulnerability. Details will appear in the proceedings of CCS 24.
