This issue is fixed in macOS Ventura 13.5. There are no known workarounds for this vulnerability.Ī downgrade issue affecting Intel-based Mac computers was addressed with additional code-signing restrictions. Users will need to recompile their applications against the patched libraries to be protected from this vulnerability. The issue has been addressed in version 0.19.3 and the current master branch. This opens up the possibility for a side-channel attacker to be notified for every unaligned memory access performed by the enclave. Second, Open Enclave SDK does not sanitize x86's alignment check flag `RFLAGS.AC` on enclave entry. Please find more details in the guidance from Intel in the references. ![]() This makes applications vulnerable to MXCSR Configuration Dependent Timing (MCDT) attacks, where incorrect `MXCSR` values can impact instruction retirement by at most one cycle, depending on the (secret) data operand value. ![]() First, Open Enclave SDK does not properly sanitize the `MXCSR` register on enclave entry. There are two issues that are mitigated in version 0.19.3. Open Enclave is a hardware-agnostic open source library for developing applications that utilize Hardware-based Trusted Execution Environments, also known as Enclaves. ![]()
