CVE-2024-1543

The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a side-channel attacker with cache-line resolution. In a controlled environment such as Intel SGX, an attacker can gain a per instruction sub-cache-line resolution allowing them to break the cache-line-level protection. For details on the attack refer to: https://doi.org/10.46586/tches.v2024.i1.457-500

Summary		(es) La implementación de T-Table protegida por canal lateral en wolfSSL hasta la versión 5.6.5 protege contra un atacante de canal lateral con resolución de línea de caché. En un entorno controlado como Intel SGX, un atacante puede obtener una resolución de línea de subcaché por instrucción que le permita romper la protección a nivel de línea de caché.
