Description Boricua 2011-07-17 11:57:25 UTC
Description of problem: When trying to open a .pdf in Firefox 5 with the mozppluger plugin enabled, Selinux appears to prevent it and sends the message I copied into the Summary space. I'm not sure if the real culprit is colord or Selinux, but the latter states this situation as a bug. Meanwhile, I applied a Selinux troubleshooter's suggested temporal workaround that seems to work.

Version-Release number of selected component (if applicable):


How reproducible: Each time I try to open a pdf via Firefox.

Steps to Reproduce:
1.Click a .pdf link within Firefox.
2.A second tab appears in black, instead of showing the .pdf.
3.Selinux alert shows up.
  
Actual results: No .pdf shown.

Expected results: .pdf displayed in Firefox's tab.

Additional info: I'm including Selinux full report:

SELinux is preventing /usr/libexec/colord from getattr access on the file /usr/local/Brother/sane/models3/ext4.ini.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that colord should be allowed getattr access on the ext4.ini 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 colord /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Reassigning to selinux-policy, although the brother drivers probably should install their stuff in the right place. I'll leave it to Dan to decide.

Comment 2 Daniel Walsh 2011-11-15 14:12:53 UTC
Already fixed.
