CVE-2012-5513

The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range.

XEN has been updated to fix various bugs and security issues:

* 

  CVE-2013-0153: (XSA 36) To avoid an erratum in early hardware, the
  Xen AMD IOMMU code by default choose to use a single interrupt
  remapping table for the whole system. This sharing implied that any
  guest with a passed through PCI device that is bus mastering capable
  can inject interrupts into other guests, including domain 0. This has
  been disabled for AMD chipsets not capable of it.

* 

  CVE-2012-6075: qemu: The e1000 had overflows under some conditions,
  potentially corrupting memory.

* 

  CVE-2013-0154: (XSA 37) Hypervisor crash due to incorrect ASSERT
  (debug build only)

* 

  CVE-2012-5634: (XSA-33) A VT-d interrupt remapping source validation
  flaw was fixed.

Also the following bugs have been fixed:

* bnc#805094 - xen hot plug attach/detach fails
* bnc#802690 - domain locking can prevent a live migration from
  completing
* bnc#797014 - no way to control live migrations
      o fix logic error in stdiostream_progress
      o restore logging in xc_save
      o add options to control migration tunables
