Description Stefan Behte (RETIRED) gentoo-dev Security 2009-04-23 16:34:43 UTC
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.
