Debian Security Advisory DSA-3794-2                   security@debian.org

Package        : munin
Debian Bug     : 856455

The update for munin issues as DSA-3794-1 caused a regression in the
zooming functionality in munin-cgi-graph. Updated packages are now
available to correct this issue. For reference, the original advisory
text follows.

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+deb8u2.

For the unstable distribution (sid), this problem has been fixed in
version 2.0.32-1.

We recommend that you upgrade your munin packages.
