    Package : xen
    CVE ID : CVE-2020-29479 CVE-2020-29480 CVE-2020-29481 CVE-2020-29482
    CVE-2020-29483 CVE-2020-29484 CVE-2020-29485 CVE-2020-29486
    CVE-2020-29566 CVE-2020-29570 CVE-2020-29571

    Multiple vulnerabilities have been discovered in the Xen hypervisor:

    Several security issues affecting Xenstore could result in cross
    domain access (denial of service, information leaks or privilege
    escalation) or denial of service against xenstored.

    Additional vulnerabilities could result in guest-to-host denial of
    service.

    For the stable distribution (buster), these problems have been fixed in
    version 4.11.4+57-g41a822c392-2.

    We recommend that you upgrade your xen packages.

    For the detailed security status of xen please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/xen
