VCID-9pe3-67b4-yqae
Aliases: CVE-2019-14859 GHSA-8qxj-f9rh-9fg2 PYSEC-2020-163 |
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. |
Affected by 2 other vulnerabilities. Affected by 1 other vulnerability. |

Aliases: CVE-2019-14853 GHSA-2mrj-435v-c2cr GHSA-pwfw-mgfj-7g3g PYSEC-2019-177 |
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. |
