CVE-2019-14859

Priority
Description
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.
