"Christoph Biedl discovered two denial of service vulnerabilities in
munin, a network-wide graphing framework. The Common Vulnerabilities
and Exposures project identifies the following problems :

  - CVE-2013-6048
    The Munin::Master::Node module of munin does not
    properly validate certain data a node sends. A malicious
    node might exploit this to drive the munin-html process
    into an infinite loop with memory exhaustion on the
    munin master.

  - CVE-2013-6359
    A malicious node, with a plugin enabled using
    'multigraph' as a multigraph service name, can abort
    data collection for the entire node the plugin runs on."
