Description Aaron Lippold 2010-08-15 21:58:19 UTC

SELinux is preventing /usr/lib/nspluginwrapper/npviewer.bin "unlink" access on

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:

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

Comment 1 Miroslav Grepl 2010-08-16 11:17:18 UTC
Looks like ~/.xine should get context.

Comment 2 Miroslav Grepl 2010-08-16 11:28:31 UTC
I would suggest to add

HOME_DIR/\.xine(/.*)?                  gen_context(system_u:object_r:nsplugin_home_t,s0)

Comment 3 Daniel Walsh 2010-08-16 11:41:51 UTC
Or should it be gnome config?

Comment 4 Miroslav Grepl 2010-08-16 11:53:23 UTC
Gnome config is also fine and actually better.
