CVE-2009-0028 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0028):
  The clone system call in the Linux kernel 2.6.28 and earlier allows
  local users to send arbitrary signals to a parent process from an
  unprivileged child process by launching an additional child process
  with the CLONE_PARENT flag, and then letting this new process exit.
