Citrix XenServer Multiple Security Updates

Description of Problem A number of security vulnerabilities have been identified in Citrix XenServer that, depending on configuration, may allow a malicious user of a PV guest VM to crash or compromise the host. These vulnerabilities affect all currently supported versions of Citrix XenServer up ...

x86: Inconsistent PV IOMMU discipline

ISSUE DESCRIPTION In order for a PV domain to set up DMA from a passed-through device to one of its pages, the page must be mapped in the IOMMU. On the other hand, before a PV page may be used as a "special" page type such as a pagetable or descriptor table, it must not be writable in the IOMMU...

x86: PV kernel context switch corruption

ISSUE DESCRIPTION On hardware supporting the fsgsbase feature, 64bit PV guests can set and clear the applicable control bit in its virtualised %cr4, but the feature remains fully active in hardware. Therefore, the associated instructions are actually usable. Linux, which does not currently suppor...

x86 shadow: Insufficient TLB flushing when using PCID

ISSUE DESCRIPTION Use of Process Context Identifiers PCID was introduced into Xen in order to improve performance after XSA-254 and in particular its Meltdown sub-issue. This enablement implied changes to the TLB flushing logic. One aspect which was overlooked is the safety of switching between...

x86/PV: page type reference counting issue with failed IOMMU update

ISSUE DESCRIPTION When an x86 PV domain has a passed-through PCI device assigned, IOMMU mappings may need to be updated when the type of a particular page changes. Such an IOMMU operation may fail. In the event of failure, while at present the affected guest would be forcibly crashed, the already...

x86: steal_page violates page_struct access discipline

ISSUE DESCRIPTION Xen's reference counting rules were designed to allow pages to change owner and state without requiring a global lock. Each page has a page structure, and a very specific set of access disciplines must be observed to ensure that pages are freed properly, and that no writable...

race with pass-through device hotplug

ISSUE DESCRIPTION When adding a passed-through PCI device to a domain after it was already started, IOMMU page tables may need constructing on the fly. For PV guests the decision whether a page ought to have a mapping is based on whether the page is writable, to prevent IOMMU access to things lik...

missing preemption in x86 PV page table unvalidation

ISSUE DESCRIPTION XSA-273 changes required, among other things, making any PTE updates restartable. The changes making PTE updates restartable assumed that L2 pagetables would always be promoted preemptibly; but this turns out not to be the case when using the 'linear pagetable' feature; the resu...
