Detail
| Multiple vulnerabilities have been discovered in the Xen hypervisor: CVE-2018-7540 Jann Horn discovered that missing checks in page table freeing may result in denial of service. CVE-2018-7541 Jan Beulich discovered that incorrect error handling in grant table checks may result in guest-to-host denial of service and potentially privilege escalation. CVE-2018-7542 Ian Jackson discovered that insufficient handling of x86 PVH guests without local APICs may result in guest-to-host denial of service. For the stable distribution (stretch), these problems have been fixed in version 4.8.3+comet2+shim4.10.0+comet3-1+deb9u5. We recommend that you upgrade your xen packages.
