Descriptions

An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. An adversary with access to precise enough information about memory accesses (typically, an untrusted operating system attacking a secure enclave) can recover an RSA private key after observing the victim performing a single private-key operation, if the window size (MBEDTLS_MPI_WINDOW_SIZE) used for the exponentiation is 3 or smaller.

Se descubrió un problema en Mbed TLS anterior a 2.28.2 y 3.x anterior a 3.3.0. Un adversario con acceso a información suficientemente precisa sobre los accesos a la memoria (normalmente, un sistema operativo no confiable que ataca un enclave seguro) puede recuperar una clave privada RSA después de observar a la víctima realizando una única operación con clave privada, si el tamaño de la ventana (MBEDTLS_MPI_WINDOW_SIZE) utilizada para la exponenciación es 3 o menor.

Multiple vulnerabilities have been discovered in Mbed TLS, the worst of which could lead to information disclosure or denial of service. Versions greater than or equal to 2.28.7 are affected.
