Description

[ Christoph Biedl ]

  • munin-node: more secure state file handling, introducing a new plugin state directory root, owned by uid 0. Then each plugin runs in its own UID plugin state directory, owned by that UID. (Closes: #684075), (Closes: #679897), closes CVE-2012-3512.

  • plugins: use runtime $ENV{MUNIN_PLUGSTATE}. So all properly written plugins will use /var/lib/munin-node/plugin-state/$uid/$some_file now - please report plugins that are still using /var/lib/munin/plugin-state/ - as those might pose a security risk!

  • Validate multigraph plugin name, CVE-2013-6048.

  • Don't abort data collection for a node due to malicious node, fixing munin#1397, CVE-2013-6359.
