Debian Security Advisory DSA-3794-3 security@debian.org

Package : munin
Debian Bug : 856536
The update for munin issued as DSA-3794-2 caused a regression leading to
Perl warnings being appended to the munin-cgi-graph log file. 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+deb8u3.
We recommend that you upgrade your munin packages.
