Description Kurt Driver 2010-06-25 01:11:35 UTC
Summary:

SELinux is preventing /usr/lib64/nspluginwrapper/npviewer.bin access to a leaked
/root/.mozilla/firefox/k4sppwp7.default/.parentlock file descriptor.

Detailed Description:

[npviewer.bin has a permissive type (nsplugin_t). This access was not denied.]

SELinux denied access requested by the npviewer.bin command. It looks like this
is either a leaked descriptor or npviewer.bin output was redirected to a file it
is not allowed to access. Leaks usually can be ignored since SELinux is just
closing the leak and reporting the error. The application does not use the
descriptor, so it will run properly. If this is a redirection, you will not get
output in the /root/.mozilla/firefox/k4sppwp7.default/.parentlock. You should
generate a bugzilla on selinux-policy, and it will get routed to the appropriate
package. You can safely ignore this avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385)

Comment 1 Daniel Walsh 2010-06-25 19:39:15 UTC
We do not support running tools like firefox as root, it is not a good idea and SELinux policy will not be changed to allow it.
