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
