|---|---|---|---|---|---|---|
| CVE-2019-14859 | A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions. | [email protected] | 9.1 | 1.60% | 2020-01-02 | 2026-06-16 |
| CVE-2019-14853 | An error-handling flaw was found in python-ecdsa before version 0.13.3. During signature decoding, malformed DER signatures could raise unexpected exceptions (or no exceptions at all), which could lead to a denial of service. | [email protected] | 7.5 | 2.50% | 2019-11-26 | 2026-06-16 |
