Comment 2 Joshua Padman 2017-11-23 05:59:38 UTC 
Versions 5.7.x are vulnerable too.

Conditions exist in OSP11/12 package collectd-5.7.2-1.1.el7ost. Still completing analysis.
Comment 3 Joshua Padman 2017-11-24 05:59:18 UTC 
Still determining severity for OSP. collectd was tech preview in 7-9 so marking won't fix for those.
Comment 4 Joshua Padman 2017-11-26 22:10:26 UTC 
collectd is in tech preview in OSP10 as well, marked accordingly.

Fixing in OSP11-12 partly because the security risk but also as a reasonable use case also has potential to crash the application.
