    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:
