CVE-2009-4271 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-4271):
  The Linux kernel 2.6.9 through 2.6.17 on the x86_64 and amd64
  platforms allows local users to cause a denial of service (panic) via
  a 32-bit application that calls mprotect on its Virtual Dynamic
  Shared Object (VDSO) page and then triggers a segmentation fault.
