Description Matěj Cepl 2008-03-31 21:08:20 UTC
Description of problem:

This happened when opening http://news.bbc.co.uk/2/hi/science/nature/7322113.stm
(however, the movie clip was normally presented and could be played).

Souhrn:

SELinux is preventing npviewer.bin (nsplugin_t) "read" to ./.fonts.conf
(user_fonts_config_t).

Podrobný popis:

SELinux denied access requested by npviewer.bin. It is not expected that this
access is required by npviewer.bin and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Povolení přístupu:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for ./.fonts.conf,

restorecon -v './.fonts.conf'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Additional info:
I really don't know whom to blame for this -- whether too eager-to-deny SELinux
policy for nspluginwrapper or nspluginwiever which does things which are not good.
