CVE-2019-14853 1 Python-ecdsa Project 1 Python-ecdsa 2023-12-10 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.
CVE-2019-14859 2 Python-ecdsa Project, Redhat 4 Python-ecdsa, Ceph Storage, Openstack and 1 more 2023-12-10 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.
