Today's rawhide -- SELinux is preventing /usr/lib/firefox-2.0.0.3/firefox-bin from loading /usr/lib/mozilla/plugins/libvlcplugin.so which requires text relocation.



Summary
   SELinux is preventing /usr/lib/firefox-2.0.0.3/firefox-bin from loading
   /usr/lib/mozilla/plugins/libvlcplugin.so which requires text relocation.

Detailed Description
   The /usr/lib/firefox-2.0.0.3/firefox-bin application attempted to load
   /usr/lib/mozilla/plugins/libvlcplugin.so which requires text relocation.
   This is a potential security problem. Most libraries do not need this
   permission. Libraries are sometimes coded incorrectly and request this
   permission.  The http://people.redhat.com/drepper/selinux-mem.html web page
   explains how to remove this requirement.  You can configure SELinux
   temporarily to allow /usr/lib/mozilla/plugins/libvlcplugin.so to use
   relocation as a workaround, until the library is fixed. Please file a
   http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

Allowing Access
   If you trust /usr/lib/mozilla/plugins/libvlcplugin.so to run correctly, you
   can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
   /usr/lib/mozilla/plugins/libvlcplugin.so"

   The following command will allow this access:
   chcon -t textrel_shlib_t /usr/lib/mozilla/plugins/libvlcplugin.so
