CVE-2009-1338 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1338):
  The kill_something_info function in kernel/signal.c in the Linux
  kernel before 2.6.28 does not consider PID namespaces when processing
  signals directed to PID -1, which allows local users to bypass the
  intended namespace isolation, and send arbitrary signals to all
  processes in all namespaces, via a kill command.
