Intel IPP is used by Intel Software Guard Extension (SGX), and Intel is releasing software updates to mitigate this potential vulnerability. Vulnerability Details: CVEID: CVE-2021-0001 Description: Observable timing discrepancy in Intel(R) IPP before version 2020 update 1 may allow authorized user to potentially enable information disclosure via local access. CVSS Base Score: 2.5 Low CVSS Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N Affected Products: . Intel IPP releases before 2020 update 1. . Intel SGX PSW for Windows v2.12.100.4 and earlier. . Intel SGX SDK for Windows v2.12.100.4 and earlier. . Intel SGX DCAP for Windows v1.10.100.4 and earlier. . Intel SGX PSW for Linux v2.13.100.4 and earlier. . Intel SGX SDK for Linux v2.13.100.4 and earlier. . Intel SGX DCAP for Linux v1.10.100.4 and earlier. Recommendations: Intel recommends that users of Intel IPP update to 2020 update 1 or later. Updates are available for download at this location: https://github.com/intel/ ipp-crypto/ Intel recommends updating the SGX software below; the updated SGX software will include mitigations for the IPP issue and are currently scheduled to be available by May 14, 2021. Intel SGX PSW for Windows to version 2.12.103 or later: https://registrationcenter.intel.com/en/products/download/3406/ Intel SGX SDK for Windows to version 2.12.103 or later: https://registrationcenter.intel.com/en/products/download/3407/ Intel SGX DCAP for Windows to version 1.10.103 or later: https://registrationcenter.intel.com/en/products/download/3610/ Intel SGX PSW for Linux to version 2.13.103 or later: https://01.org/intel-software-guard-extensions/downloads Intel SGX SDK for Linux to version 2.13.103 or later: https://01.org/intel-software-guard-extensions/downloads Intel SGX DCAP for Linux to version 1.10.103 or later: https://01.org/intel-software-guard-extensions/downloads To address this issue, an SGX TCB recovery is planned for Q2 2021. Customers will require the software update to get successful attestation responses. For customers using the Intel Attestation Service (IAS), the IAS Development Environment (DEV) will enforce the software updates beginning June 15, 2021 and the IAS Production Environment (LIV) will enforce the updates beginning July 13, 2021. For customers that are not using IAS, but instead are constructing their own attestation infrastructure using the Intel SGX Provisioning Certificate Service (PCS), updated Endorsements/Reference Values (i.e., PCK Certificates and verification collateral) will be available June 8, 2021. These customers decide when to enforce the software update, as part of their Appraisal Policies. Refer to Intel SGX Attestation Technical Details for more information on the SGX TCB recovery process. Further TCB Recovery Guidance for developers is available. Acknowledgements: Intel would like to thank Tuba Yavuz, Farhaan Fowze, Ken (Yihang) Bai, Grant Hernandez, Kevin Butler and Dave Tian from University of Florida for reporting this issue. Intel, and nearly the entire technology industry, follows a disclosure practice called Coordinated Disclosure, under which a cybersecurity vulnerability is generally publicly disclosed only after mitigations are available.
