munin - denial of service

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.

For the stable distribution (wheezy), these problems have been fixed in
version 2.0.6-4+deb7u2.

For the testing distribution (jessie), these problems have been fixed in
version 2.0.18-1.

For the unstable distribution (sid), these problems have been fixed in
version 2.0.18-1.

We recommend that you upgrade your munin packages.
