CVE-2020-0981

Estado: ModificadaAlta (8.8)—

Hay una vulnerabilidad de omisión de la característica de seguridad cuando Windows da un fallo al no manejar apropiadamente las relaciones de token. Un atacante que explotara con éxito la vulnerabilidad podría permitir que una aplicación con un determinado nivel de integridad ejecute código con un nivel de integridad diferente, conllevando a un escape del sandbox. La actualización aborda la vulnerabilidad al corregir la manera en que Windows maneja las relaciones de token, también se conoce como "Windows Token Security Feature Bypass Vulnerability".

CVSS
