CVE-2009-1338

First published: Thu Apr 16 2009(Updated: )

Description of problem: Currently "kill &lt;sig&gt; -1" kills processes in all namespaces and breaks the isolation of namespaces. Use "task_pid_vnr() &gt; 1" to check since task_pid_vnr() returns 0 if process is outside the caller's namespace. Upstream patch: <a href="http://git.kernel.org/linus/d25141a818383b3c3b09f065698c544a7a0ec6e7">http://git.kernel.org/linus/d25141a818383b3c3b09f065698c544a7a0ec6e7</a>
