CVE-2014-1950 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-1950):
  Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x
  through 4.3.x, when using a multithreaded toolstack, does not properly
  handle a failure by the xc_cpumap_alloc function, which allows local users
  with access to management functions to cause a denial of service (heap
  corruption) and possibly gain privileges via unspecified vectors.
