This update ships updated CPU microcode for some types of Intel CPUs. In particular it provides mitigations for the TAA (TSX Asynchronous Abort) vulnerability. For affected CPUs, to fully mitigate the vulnerability it is also necessary to update the Linux kernel packages as released in DLA 1989-1.

For Debian 8 Jessie, these problems have been fixed in version 3.20191115.2~deb8u1.

We recommend that you upgrade your intel-microcode packages.
