23 Aug 2021 — An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). A NULL algorithm parameters entry looks identical to an array of REAL (size zero) and thus the certificate is considered valid. However, if the parameters do not match in any way, then the certificate should be considered invalid. Se ha detectado un problema en Mbed TLS versiones anteriores a 2.25.0 (y versiones anteriores a 2.16.9 LTS y versiones anteriores a 2.7.18 LTS).

19 Jul 2021 — 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.
