https://notcve.org/view.php?id=CVE-2020-15522
20 May 2021 — Bouncy Castle BC Java before 1.66, BC C# .NET before 1.8.7, BC-FJA before 1.0.1.2, 1.0.2.1, and BC-FNA before 1.0.1.1 have a timing issue within the EC math library that can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures. Bouncy Castle BC Java versiones anteriores a 1.66, BC C # .NET versiones anteriores a 1.8.7, BC-FJA versiones anteriores a 1.0.1.2, 1.0.2.1 y BC-FNA versiones anteriores a 1.0.1.1... • https://github.com/bcgit/bc-csharp/wiki/CVE-2020-15522 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
