Package        : munin
Vulnerability  : denial of service
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2013-6048 CVE-2013-6359

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.
