To fully resolve these vulnerabilities it is also necessary to update the Linux kernel packages as released in DSA 4444.

For the stable distribution (stretch), these problems have been fixed in version 3.20190514.1~deb9u1.

We recommend that you upgrade your intel-microcode packages.

For the detailed security status of intel-microcode please refer to its security tracker page at: [link moved to references]");
