dynazoom graph not working with munin-cgi-graph after recent security fix
Last modified: 2017-08-28 13:00:57 EDT
Description of problem:
When dynamic graph is being open via dynazoom it sends upper and lower limits to generate the graph images as empty values. This fails since the fix in parsing of input parameters of munin-cgi-graph. This has been however solved in the upstream stable-2.0 branch already.
Version-Release number of selected component (if applicable):
Install munin-2.0.30-5.fc26.noarch and open some graph in detail view - via dynazoom.html.
Steps to Reproduce:
1. Open munin web interface
2. Select some host
3. Select some monitored service graph
4. Select some time range graph
dynazoom.html is opened, but munin-cgi-graph image is not rendered.
dynazoom.html is opened and munin-cgi-graph image is rendered and displayed.
Debug information shows that upper_limit received an empty value and has been passed to rrdtool. This is already fixed in upstream ( just few days after initial security fix ) so munin-cgi-graph checks whether it received numerical value in upper/lower_limit parameters.
I have the same issue. I think it's down to this:
2017/08/28 17:24:03 [RRD ERROR] Unable to graph @@CGITMPDIR@@/munin-cgi-graph/wobble.com/wibble.wobble.com/sensors_temp-pinpoint=1469376632,1503936632.png?&lower_limit=&upper_limit=&size_x=800&size_y=400 : option -l - Cannot convert '' to float
Which I think has been closed upstream by:
so we need a version bump?
