others which are substantially similar) is permitted during the
embargo, even on public-facing systems with untrusted guest users and

But: Distribution of updated software is prohibited (except to other
members of the predisclosure list).

Predisclosure list members who wish to deploy significantly different
patches and/or mitigations, please contact the Xen Project Security

post-embargo publicly released Xen Project advisories, even though it
