Descriptions

In Mbed TLS before 2.28.0 and 3.x before 3.1.0, psa_cipher_generate_iv and psa_cipher_encrypt allow policy bypass or oracle-based decryption when the output buffer is at memory locations accessible to an untrusted application.

En Mbed TLS versiones anteriores a 2.28.0 y 3.x versiones anteriores a 3.1.0, las funciones psa_cipher_generate_iv y psa_cipher_encrypt permiten omitir la política o el descifrado basado en oráculos cuando el búfer de salida es encontrado en ubicaciones de memoria accesibles para una aplicación no confiable

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.
