Package : xen
CVE ID : CVE-2018-7540 CVE-2018-7541 CVE-2018-7542

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.
