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. Published: January 02, 2020; 10:15:11 AM -0500 |
V4.0:(not available) V3.1: 9.1 CRITICAL V2.0: 6.4 MEDIUM |
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. Published: November 26, 2019; 8:15:10 AM -0500 |
