Description:
An issue (known as XSA-212) was discovered in Xen, with fixes available for
4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an
insufficient check on XENMEM_exchange input, allowing the caller to drive
hypervisor memory accesses outside of the guest provided input/output
arrays.
