[OSSA 2014-002] Swift TempURL timing attack (CVE-2014-0006)
by Thierry Carrez 17 Jan '14

17 Jan '14

OpenStack Security Advisory: 2014-002 CVE: CVE-2014-0006 Date: January 16, 2013 Title: Swift TempURL timing attack Reporter: Samuel Merritt (SwiftStack) Products: Swift Affects: All supported versions Description: Samuel Merritt from SwiftStack reported a timing attack vulnerability in Swift TempURL middleware. By analyzing response times to arbitrary TempURL requests, an attacker may be able to guess valid secret URLs and get access to objects that were only intended to be publicly shared with specific recipients. In order to use this attack, the attacker needs to know the targeted object name, and the object account needs to have a TempURL key set. Only Swift setups enabling the TempURL middleware are affected. Icehouse (development branch) fix: https://review.openstack.org/#/c/67185/ Havana (1.10.0) fix: https://review.openstack.org/#/c/67186/ Grizzly (1.8.0) fix: https://review.openstack.org/#/c/67187/ Note: the Icehouse fix will be included in upcoming 1.12.0 release.

[OSSA 2014-001] Nova live snapshots use an insecure local directory (CVE-2013-7048)
by Thierry Carrez 13 Jan '14

OpenStack Security Advisory: 2014-001 CVE: CVE-2013-7048 Date: January 13, 2013 Title: Nova live snapshots use an insecure local directory Reporter: Daniel Berrange (Red Hat) Products: Nova Affects: Grizzly and later Description: Daniel Berrange from Red Hat reported that the directories used to temporarily store live snapshots on Nova compute nodes were writable to all local users. A local attacker with shell access on compute nodes could therefore read and modify the contents of live snapshots before those are uploaded to the image service.

OpenStack “J” naming poll closed <http://lists.openstack.org/pipermail/openstack/2013-December/004035.html> Polls closed, the OpenStack community decided: Juno will be the name of the OpenStack development cycle starting in May 2014, after the Icehouse cycle completes. Third party testing with Turbo-Hipster <http://josh.people.rcbops.com/2013/12/third-party-testing-with-turbo-hipste…> Soon you are going to see a new robot barista leaving comments on Nova code reviews. He is obsessed with espresso, that band you haven’t heard of yet, and easing the life of OpenStack operators. Doing a large OpenStack deployment has always been hard when it came to database migrations. Running a migration requires downtime, and when you have giant datasets that downtime could be hours. To help catch these issues a <http://josh.people.rcbops.com/2013/09/building-a>new zuul worker <http://josh.people.rcbops.com/2013/09/building-a-zuul-worker/> called Turbo-Hipster will run your patchset’s migrations against copies of real databases. This will give you valuable feedback on the success of the patch, and how long it might take to migrate.

[OSSA 2013-037] Nova compute DoS through ephemeral disk backing files (CVE-2013-6437)
by Thierry Carrez 18 Dec '13

18 Dec '13

OpenStack Security Advisory: 2013-037 CVE: CVE-2013-6437 Date: December 18, 2013 Title: Nova compute DoS through ephemeral disk backing files Reporter: Phil Day (HP) Products: Nova Affects: All supported versions Description: Phil Day from HP reported a vulnerability in the libvirt driver handling of ephemeral disk backing files on Nova compute nodes. By repeatedly creating snapshots, changing the os_type to a new random value, and spawning new instances from the snapshot (and quickly deleting those instances), an authenticated user could generate lots of different ephemeral disk backing files and fill up compute node disks, potentially resulting in a Denial of Service against a Nova setup. Only Nova setups running the libvirt driver are affected.

OpenStack 2013.2.1 released
by Alan Pevec 17 Dec '13

17 Dec '13

Hello everyone, The OpenStack Stable Maintenance team is happy to announce the release of the 2013.2.1 stable Havana release. We have been busy reviewing and accepting backported bugfixes to the stable/havana branches according to the criteria set at: https://wiki.openstack.org/wiki/StableBranch A total of 136 bugs have been fixed across all projects. These updates to Havana are intended to be relatively risk free with no intentional regressions or API changes. The list of bugs, tarballs and other milestone information for each project may be found on Launchpad: https://launchpad.net/nova/havana/2013.2.1 https://launchpad.net/keystone/havana/2013.2.1 https://launchpad.net/glance/havana/2013.2.1 https://launchpad.net/neutron/havana/2013.2.1 https://launchpad.net/cinder/havana/2013.2.1 https://launchpad.net/horizon/havana/2013.2.1 https://launchpad.net/heat/havana/2013.2.1 https://launchpad.net/ceilometer/havana/2013.2.1 Release notes may be found on the wiki: https://wiki.openstack.org/wiki/ReleaseNotes/2013.2.1 The freeze on the stable/havana branches will be lifted today as we begin working toward the 2013.2.2 release, to be released on Feb 06 and managed by Adam Gandelman. Thanks, Alan

[Swift] Release of Swift 1.11.0
by John Dickinson 13 Dec '13

13 Dec '13

I'm happy to announce that we've released Swift 1.11.0. You can find the high-level Launchpad details (including a link to the tarball) at https://launchpad.net/swift/icehouse/1.11.0. As always, you can upgrade to this release without any downtime to your users. Swift 1.11.0 is the work of 26 contributors, including the following 5 new contributors to Swift: Rick Hawkins Steven Lang Gonéri Le Bouder Zhenguo Niu Aaron Rosen This release includes some significant new features. I encourage you to read the change log (https://github.com/openstack/swift/blob/master/CHANGELOG) and I'll highlight some of the more significant changes below. * Discoverable capabilities: The Swift proxy server will now respond to /info requests with information about the particular cluster being queried. This will allow easy programmatic discovery of limits and features implemented in a particular Swift system. The first two obvious use cases are for cross-cluster clients (e.g. common client between Rackspace, HP, and a private deployment) and for deeper functional testing of all parts of the Swift API. * Early quorum response: On writes, the Swift proxy server will not return success unless a quorum of the storage nodes indicate they have successfully written data to disk. Previously, the proxy waited for all storage nodes to respond, even if it had already heard from a quorum of servers. With this change, the proxy node will be able to respond to client requests as soon as a quorum of the storage nodes indicate a common response. This can help lower response times to clients and improve performance of the cluster. * Retry reads: If a storage server fails during an object read request, the proxy will now continue the response stream to the client by making a request to a different replica of the data. For example, if a client requests a 3GB object and the particular object server serving the response fails during the request after 1.25GB, the proxy will make a range request to a different replica, asking for the data starting at 1.25GB into the file. In this way, Swift provides even higher availability to your data in the face of hardware failures. * DiskFile API: The DiskFile abstraction for talking to data on disk has been refactored to allow alternate implementations to be developed. There is an example in-memory implementation included in the codebase. External implementations include one for Gluster and one for Seagate Kinetic drives. The DiskFile API is still a work in progress and is not yet finalized. * Object replication ssync (an rsync alternative): A Swift storage node can now be configured to use Swift primitives for replication transport instead of rsync. Although still being tested at scale, this mechanism will allow for future development improving replication times and lowering both MTTD and MTTR of errors. I'd like to publicly thank the Swift contributors and core developers for their work on Swift. Their diverse experience and viewpoints make Swift the mature project it is, capable of running the world's largest storage clouds. --John
