Malicious plugin can abort data collection for a node
|Reported by:||cbiedl||Owned by:||nobody|
using "multigraph" as a multigraph service name is not accepted by
Munin::Master::Node. The check however dies (in config) or croaks
(in fetch), causing in the connection being dropped and no data
gathered for that node. That's a bit harsh.
The patch below lowers that situation to two error messages.
Impact is rather small as this affects the data for that node itself.
A malicious plugin still does harm, but if an evil guy is able to
control which plugins are run on a node, no longer collecting munin
data for that one is not one of the bigger concerns.
