Summary

Stevie Trujillo discovered a local file write vulnerability in munin, a
network-wide graphing framework, when CGI graphs are enabled. GET
parameters are not properly handled, allowing to inject options into
munin-cgi-graph and overwriting any file accessible by the user running
the cgi-process.

For the stable distribution (jessie), this problem has been fixed in
version 2.0.25-1+deb8u3.

We recommend that you upgrade your munin packages.
