Updated python-ecdsa packages fix security vulnerabilities: It was discovered that python-ecdsa incorrectly handled certain signatures. A remote attacker could possibly use this issue to cause python-ecdsa to generate unexpected exceptions, resulting in a denial of service (CVE-2019-14853). It was discovered that python-ecdsa incorrectly verified DER encoding in signatures. A remote attacker could use this issue to perform certain malleability attacks (CVE-2019-14859).
