[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

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. Icehouse (development branch) fix: https://review.openstack.org/#/c/58852/ Havana fix: https://review.openstack.org/#/c/60548/ Grizzly fix: https://review.openstack.org/#/c/60550/ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-7048 https://bugs.launchpad.net/nova/+bug/1227027 Regards, -- Thierry Carrez OpenStack Vulnerability Management Team

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. How to Upgrade an OpenStack Swift Cluster with No Downtime <http://swiftstack.com/blog/2013/12/20/upgrade-openstack-swift-no-downtime/> OpenStack Swift deployers can upgrade from one version of Swift to the next with zero downtime for end users. This has been supported since the initial release of OpenStack Swift back in 2010.

[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. Icehouse (development branch) fix: https://review.openstack.org/62910 Havana fix: https://review.openstack.org/62912 Grizzly fix: https://review.openstack.org/62913 References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-6437 https://bugs.launchpad.net/nova/+bug/1253980 Regards, -- Thierry Carrez OpenStack Vulnerability Management Team
