## Abstract
Cloud computing has emerged as a corner stone of today's computing landscape. More and more customers who outsource their infrastructure benefit from the manageability, scalability and cost saving that come with cloud computing. Those benefits get amplified by the trend towards microservices. Instead of renting and maintaining full VMs, customers increasingly leverage container technologies, which come with a much more light

CVE-2017-10912 xsa217 xen: page transfer may allow PV guest to elevate privilege (XSA-217)
ISSUE DESCRIPTION
Domains controlling other domains are permitted to map pages owned by
the domain being controlled. If the controlling domain unmaps such a
page without flushing the TLB, and if soon after the domain being
controlled transfers this page to another PV domain (via
GNTTABOP_transfer or, indirectly, XENMEM_exchange), and that third
domain uses the page as a page table, the controlling domain will have
write access to a live page table until the applicable TLB entry is
flushed or evicted. Note that the domain being controlled is
necessarily HVM, while the controlling domain is PV.
IMPACT
A malicious pair of guests may be able to access all of system memory,
allowing for all of privile
