CVE-2009-0835 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0835):
  The __secure_computing function in kernel/seccomp.c in the seccomp
  subsystem in the Linux kernel 2.6.28.7 and earlier on the x86_64
  platform, when CONFIG_SECCOMP is enabled, does not properly handle
  (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process
  making a 32-bit syscall, which allows local users to bypass intended
  access restrictions via crafted syscalls that are misinterpreted as
  (a) stat or (b) chmod, a related issue to CVE-2009-0342 and
  CVE-2009-0343.
