AVC everytime I launch a tab in firefox from gnome-terminal

[Chuck Anderson]

Every time I launch a tab from a URL in gnome-terminal, I get this 
AVC:

Hmm why is this program set-uid root?

> ls -l /usr/lib/nspluginwrapper/plugin-config   
-rwsr-xr-x 1 root
root 60048 2008-03-11 10:02 /usr/lib/nspluginwrapper/plugin-config*


Summary:

SELinux is preventing plugin-config (nsplugin_config_t) "execstack" to
<Unknown>
(nsplugin_config_t).

Detailed Description:

SELinux denied access requested by plugin-config. It is not expected that this
access is required by plugin-config 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://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.

This is probably caused
by some evil/badly written plugin

If you turn on the allow_nsplugin_execmem boolean, the app should work.

setsebool -P allow_nsplugin_execmem=1
