CVE-2020-10932

CVE-2020-10932 affects Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker able to obtain precise side‑channel measurements (often in compromised environments like SGX enclaves) can recover the long‑term ECDSA private key by exploiting side channels in scalar multiplication, convertin...

CVE-2020-10932

An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

Updated mbedtls packages fix security vulnerabilities

Updated mbedtls packages fix security vulnerabilities: If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported. Found by Alejandro Cabrera Aldaya and Billy...

FreeBSD : Mbed TLS -- Side channel attack on ECDSA (b70b880f-5727-11ea-a2f3-001cc0382b2f)

Janos Follath reports : Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it as it is smaller than RSA keys and not guaranteed to have only large prime factors, and then, by brute force, recover the key. C Tenable Network...

FreeBSD : Mbed TLS -- Cache attack against RSA key import in SGX (056ea107-5729-11ea-a2f3-001cc0382b2f)

Janos Follath reports : If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported. The attack only requires access to fine grained measurements to cache usage...
