DSA 4447-1 shipped updated CPU microcode for most types of Intel CPUs as mitigations for the MSBDS, MFBDS, MLPDS and MDSUM hardware vulnerabilities.

This update provides additional support for some Sandybridge server and Core-X CPUs which were not covered in the original May microcode release. For a list of specific CPU models now supported please refer to the entries listed under CPUID 206D6 and 206D7 at https://www.intel.com/content/dam/www/public/us/en/documents/corporate-information/SA00233-microcode-update-guidance_05132019.pdf

For the stable distribution (stretch), these problems have been fixed in version 3.20190618.1~deb9u1.

We recommend that you upgrade your intel-microcode packages.
