SELinux is preventing npviewer.bin (nsplugin_t) "search" to ./pcm (alsa_etc_rw_t) - selinux - Fedora mailing-lists

      What is npviewr?
What does it do?
Setroubleshoot reports that it is causing trouble:
Summary:
SELinux is preventing npviewer.bin (nsplugin_t)
"search" to ./pcm
(alsa_etc_rw_t).
Detailed Description:
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.
Allowing Access:
Sometimes labeling problems can cause SELinux denials.
You could try to restore
the default system file context for ./pcm,
restorecon -v './pcm'
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.
