Descriptions
An issue was discovered in Arm Mbed TLS before 2.24.0. It incorrectly uses a revocationDate check when deciding whether to honor certificate revocation via a CRL. In some situations, an attacker can exploit this by changing the local clock.
Se ha detectado un problema en Arm Mbed TLS versiones anteriores a 2.24.0. Usa incorrectamente una comprobación de revocationDate cuando decide si acepta la revocación de certificados por medio de una CRL. En algunas situaciones, un atacante puede explotar esto al cambiar el reloj local
Multiple vulnerabilities have been discovered in Mbed TLS, the worst of which could result in arbitrary code execution. Versions less than 2.28.1 are affected.
