If you run your plugins in confined mode # setsebool -P allow_unconfined_nsplugin_transition=1 # yum install nspluginwrapper # restorecon -R -v ~/ None of the plugins will be allowed to read directories like .ssh or .gpg in your home directory. firefox is really difficult to confine, but with nsplugin you can confine the plugins fairly well. > > regards > > christoph > > > ps: What is the current state of getting a real > "High-Level-Language(TM)" for SELinux configuration? - -- fedora-selinux-list mailing list fedora-selinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-selinux-list -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkf+b/4ACgkQrlYvE4MpobPs9QCfUp5K8B2Hldig0Zfi9j2Fncug aIcAoNoW0dIbzyY/+AdIuC2czZBP52E5 =mVBD -----END PGP SIGNATURE----- -- fedora-selinux-list mailing list fedora-selinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-selinux-list
