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.
