Looks like the bash is called from dnssec-triggerd and wants to access unbound-control. That would happen when dnssec-trigger calls unbound-control in ubhook.c to configure unbound forward zones and other stuff. 

I think there's no relation to dnssec-trigger-script as that build of dnssec-trigger doesn't call it directly from the daemon but later builds are, so there's a risk that this issue will get broader.

We'll need to watch for it, taking it for now because of the above. If you still has the logs, are there any details just after the selinux alert? The ubhook.c would normally report failures.

This looks like a duplicate to bug #1147705 except the Fedora branch. Not sure whether it's practical to merge them or keep them separate.

Hi folks, could you please tell me about the differneces from bug #1147705 and explain the empty or "." file name in this case? From the dnssec-triggerd side, we're just calling "system()" which in turn starts a shell with "unbound-control" plus some arguments as the command.

IMO, system() should be avoided.  Can you call fork()+exec() on unbound-control instead and avoid the intermediate bash process completely?

I don't think we're going to fix this any soon as this is how upstream works and has worked for a while now. But we can consider it when we know why is bash a problem here.

Anyway I'm curious why this hasn't been reported by others with later versions of the package. Is there a possibility that this has been already fixed?

The only difference is old version of Fedora. 
In this case there is also old version of selinux-policy package. 

Paul,
You need to update selinux-policy package, we allowed this rule.

lukas: ok, that's good enough for me.

I think I got this bug in FC22. Please reopen if you feel appropriate. I wasn't working with the iso file, so I don't know how what caused this alert.

The elinux details are below:

"SELinux is preventing pool from read access on the file antiX-15-V_x64-base.iso.

*****  Plugin mozplugger (93.0 confidence) suggests   ************************

If you want to use the plugin package

Then execute: 
restorecon -v 'antiX-15-V_x64-base.iso'


*****  Plugin catchall (1.73 confidence) suggests   **************************

If you believe that pool should be allowed read access on the antiX-15-V_x64-base.iso file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pool /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Where is this iso?  You should just need to run restorecon on it.

What firefox plugin is reading an ISO?
