File b7fcc799a-CVE-2013-4400.patch of Package libvirt.openSUSE_13.1_Update

commit b7fcc799ad5d8f3e55b89b94e599903e3c092467
Author: Daniel P. Berrange <berrange@redhat.com>
Date:   Wed Oct 9 15:14:34 2013 +0100

    Close all non-stdio FDs in virt-login-shell (CVE-2013-4400)
    
    We don't want to inherit any FDs in the new namespace
    except for the stdio FDs. Explicitly close them all,
    just in case some do not have the close-on-exec flag
    set.
