Details

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)
