Medium: munin

Issue Overview:

The get_group_tree function in lib/Munin/Master/HTMLConfig.pm in Munin before 2.0.18 allows remote nodes to cause a denial of service (infinite loop and memory consumption in the munin-html process) via crafted multigraph data.

Munin::Master::Node in Munin before 2.0.18 allows remote attackers to cause a denial of service (abort data collection for node) via a plugin that uses “multigraph” as a multigraph service name.
