Bugzilla:
496031: CVE-2009-1338 kernel: 'kill sig -1' must only apply to caller's pid namespace

The MITRE CVE dictionary describes this issue as:

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.
