Package : xen
CVE ID : CVE-2018-3665

This update provides mitigations for the "lazy FPU" vulnerability
affecting a range of Intel CPUs, which could result in leaking CPU
register states belonging to another vCPU previously scheduled on the
same CPU. For additional information please refer to
https://xenbits.xen.org/xsa/advisory-267.html

For the stable distribution (stretch), this problem has been fixed in
version 4.8.3+xsa267+shim4.10.1+xsa267-1+deb9u8.

We recommend that you upgrade your xen packages.

For the detailed security status of xen please refer to
its security tracker page at:
