Descriptions

In Go before 1.13.13 and 1.14.x before 1.14.5, Certificate.Verify may lack a check on the VerifyOptions.KeyUsages EKU requirements (if VerifyOptions.Roots equals nil and the installation is on Windows). Thus, X.509 certificate verification is incomplete.

En Go versiones anteriores a 1.13.13 y versiones 1.14.x anteriores a 1.14.5, Certificate.Verify puede carecer de una comprobación en los requisitos VerifyOptions.KeyUsages EKU (si VerifyOptions.Roots es igual a cero y la instalación está en Windows). Entonces, la verificación del certificado X.509 está incompleta

An update that solves three vulnerabilities and has four fixes is now available. This update for go1.14 fixes the following issues.
