20 Dec 2021 — Mbed TLS before 3.0.1 has a double free in certain out-of-memory conditions, as demonstrated by an mbedtls_ssl_set_session() failure. Mbed TLS versiones anteriores a 3.0.1,presenta una doble liberación en determinadas condiciones de salida de memoria, como es demostrado por un fallo de la función mbedtls_ssl_set_session() 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. • https://bugs.gentoo.org/829660 • CWE-415: Double Free •

23 Aug 2021 — An issue was discovered in Mbed TLS before 2.24.0 (and before 2.16.8 LTS and before 2.7.17 LTS). There is missing zeroization of plaintext buffers in mbedtls_ssl_read to erase unused application data from memory. Se ha detectado un problema en Mbed TLS versiones anteriores a 2.24.0 (y versiones anteriores a 2.16.8 LTS y versiones anteriores a 2.7.17 LTS). Falta la puesta a cero de los búferes de texto plano en la función mbedtls_ssl_read para borrar de la memoria los datos no usados de la aplicación.

23 Aug 2021 — An issue was discovered in Mbed TLS before 2.24.0. The verification of X.509 certificates when matching the expected common name (the cn argument of mbedtls_x509_crt_verify) with the actual certificate name is mishandled: when the subjecAltName extension is present, the expected name is compared to any name in that extension regardless of its type. This means that an attacker could impersonate a 4-byte or 16-byte domain by getting a certificate for the corresponding IPv4 or IPv6 address (this would require ... • https://github.com/ARMmbed/mbedtls/issues/3498 • CWE-295: Improper Certificate Validation •

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.

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. Usa incorrectamente una comprobación de revocationDate cuando decide si acepta la revocación de certificados por medio de una CRL. • https://bugs.gentoo.org/740108 • CWE-295: Improper Certificate Validation •
