There is no new general release planned for these versions. Recommendations: Intel recommends that users of Intel CSME, Intel TXE, Intel AMT and Intel SPS update to the latest version provided by the system manufacturer that addresses these issues. The Intel AMT SDK is available for download here . Intel has issued a Product Discontinuation notice for the Intel DAL SDK and recommends that users of the Intel DAL SDK uninstall it or discontinue use at their earliest convenience. Acknowledgements: Intel would like to thank Trammell Hudson (CVE-2020-8705), Marius Gabriel Mihai (CVE-2020-12354, CVE-2020-12304), Oussama Sahnoun (CVE-2020-12297), Rotem Sela and Brian Mastenbrook (CVE-2020-12355) for reporting these issues.
