CVE-2020-10932
https://notcve.org/view.php?id=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 channels in the conversion to affine coordinates; (2) using an attack described by Naccache, Smart, and Stern in 2003 to recover a few bits of the ephemeral scalar from those projective coordinates via several measurements; and (3) using a lattice attack to get from there to the long-term ECDSA private key used for the signatures. Typically an attacker would have sufficient access when attacking an SGX enclave and controlling the untrusted OS. Se detectó un problema en Arm Mbed TLS versiones anteriores a 2.16.6 y 2.7.x versiones anteriores a 2.7.15. Un atacante que puede obtener mediciones de canal lateral lo suficientemente precisas que puede recuperar la clave privada ECDSA a largo plazo al (1) reconstruir la coordenada proyectiva del resultado de la multiplicación escalar explotando canales laterales en la conversión a coordenadas afines; (2) usar un ataque descrito por Naccache, Smart y Stern en 2003 para recuperar algunos bits del escalar efímero de esas coordenadas proyectivas por medio de varias mediciones; y (3) usar un ataque de red para llegar desde allí a la clave privada ECDSA a largo plazo utilizada para las firmas. • https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FCWN5HIF4CJ2LZTOMEBJ7Q4IMMV7ZU2V https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZNOS2IIBH5WNJXZUV546PY7666DE7Y3L https://tls.mbed.org/tech-updates/releases/mbedtls-2.16.6-and-2.7.15-released https://tls.mbed.org/tech-updates/security-advisories https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advi • CWE-203: Observable Discrepancy CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
