CVE-2008-3527 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-3527):
  arch/i386/kernel/sysenter.c in the Virtual Dynamic Shared Objects
  (vDSO) implementation in the Linux kernel before 2.6.21 does not
  properly check boundaries, which allows local users to gain
  privileges or cause a denial of service via unspecified vectors,
  related to the install_special_mapping, syscall, and syscall32_nopage
  functions.
