| CVE-2019-14859 | 2 Python-ecdsa Project, Redhat | 4 Python-ecdsa, Ceph Storage, Openstack and 1 more | 2021-08-04 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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. | |||||
| CVE-2019-14853 | 1 Python-ecdsa Project | 1 Python-ecdsa | 2019-12-17 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
