Name of the Vulnerable Software and Affected Versions wolfSSL versions up to 5.6.5

Description The side-channel protected T-Table implementation in wolfSSL protects against a side-channel attacker with cache-line resolution. However, 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.

Recommendations For wolfSSL versions up to 5.6.5, update to a version later than 5.6.5 to resolve the issue. At the moment, there is no information about other specific mitigation measures for this vulnerability.
