Future releases will have tarball signatures. Alfredo and Andrew are
working on the new build/release tooling now.

Hash: SHA1
Last week, Red Hat investigated an intrusion on the sites of both the Ceph
community project (ceph.com) and Inktank (download.inktank.com), which
were hosted on a computer system outside of Red Hat infrastructure.
Ceph.com provided Ceph community versions downloads signed with a Ceph
signing key (id 7EBFDD5D17ED316D). Download.inktank.comprovided releases
of the Red Hat Ceph product for Ubuntu and CentOS operating systems signed
with an Inktank signing key (id 5438C7019DCEEEAD). While the investigation
into the intrusion is ongoing, our initial focus was on the integrity of
the software and distribution channel for both sites.
To date, our investigation has not discovered any compromised code or
binaries available for download on these sites. However, we cannot fully
rule out the possibility that some compromised code or binaries were
available for download at some point in the past. Further, we can no
longer trust the integrity of the Ceph signing key, and therefore have
created a new signing key (id E84AC2C0460F3994) for verifying downloads.
This new key is committed to the ceph.git repository and is
also available from
https://git.ceph.com/release.asc
The new key should look like:
pub 4096R/460F3994 2015-09-15
uid Ceph.com (release key) <security(a)ceph.com>
All future release git tags will be signed with this new key.
This intrusion did not affect other Ceph sites such as download.ceph.com
(which contained some older Ceph downloads) or git.ceph.com (which mirrors
various source repositories), and is not known to have affected any other
Ceph community infrastructure. There is no evidence that build system or
the Ceph github source repository were compromised.
New hosts for ceph.com and download.ceph.com have been created and the
sites have been rebuilt. All content available on download.ceph.com as
been verified, and all ceph.com URLs for package locations now redirect
there. There is still some content missing from download.ceph.com that
will appear later today: source tarballs will be regenerated from git, and
older release packages are being resigned with the new release key DNS
changes are still propogating so you may not see the new versions of the
ceph.com and download.ceph.com sites for another hour or so.
The download.inktank.com host has been retired and affected Red Hat
customers have been notified, further information is available at
https://securityblog.redhat.com/2015/09/17/.
Users of Ceph packages should take action as a precautionary measure to
download the newly-signed versions. Please see the instructions below.
The Ceph community would like to thank Kai Fabian for initially alerting
us to this issue.
Any questions can be directed to the email discussion lists or the #ceph
IRC channel on irc.oftc.net.
Thank you!
