Description
A side channel attack has been found on the ECDSA implementation of Mbed TLS before 2.22.0, 2.16.6 and 2.7.15, allowing a local attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) to fully recover an ECDSA private key after observing a number of signature operations.
