Red Hat Python-Ecdsa vulnerabilities

CVE-2019-14859 [CRITICAL] CWE-347 CVE-2019-14859: A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify wheth 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.
