For servers with AMD CPUs no microcode update is needed, please refer to https://xenbits.xen.org/xsa/advisory-263.html for further information. For the stable distribution (stretch), this problem has been fixed in version 4.8.3+xsa262+shim4.10.0+comet3-1+deb9u7. We recommend that you upgrade your xen packages.
