Hi Paul, Allan, @Paul, Thanks for reporting this issue. Please check the existing comments in bug 904332
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=904332 @Sven can you please help us and maybe explain how Paul should be using the cacti-spine binary with these Linux capabilities enabled that we added in that version by your patch. I guess he needs to install libcap2-bin and run $(chmod u-s /usr/sbin/spine) Paul On 26-02-2019 07:39, Paul Allen wrote: > Package: cacti-spine > Version: 1.1.37-1~bpo9+1 > Severity: normal > > Dear Maintainer, > > > * What led up to the situation? > Upgrading from cacti-spine_1.1.37-1~bpo9+1 to > cacti-spine_1.1.37-2~bpo9+1 caused execution of cacti-spine for non-root > users to break, even with setuid bits set for either just user or all. > * What exactly did you do (or not do) that was effective (or > ineffective)? > Attempted to set setuid bits on /usr/sbin/spine to permit execution > by non-root users (eg, cacti).
