Alpine: multiple py3-ecdsa packages: security update to 0.13.3-r0

critical Tenable Self-Hosted Container Security Plugin ID 406668

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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-2019-14853)

 - 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. (CVE-2019-14859)
