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.

The remote host is affected by the vulnerability described in GLSA-202409-14 (Mbed TLS: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Mbed TLS. Please review the CVE identifiers referenced     below for details.
