OpenStack Security Advisory: 2014-032 CVE: CVE-2014-3608 Date: October 2, 2014 Title: Nova VMware driver still leaks rescued images Reporter: Garth Mollett (Red Hat) Products: Nova Versions: up to 2014.1.2

Description: Garth Mollett from Red Hat reported an incomplete fix to OSSA-2014-017 (CVE-2014-2573), a vulnerability affecting Nova. If an authenticated user places an instance into rescue, and then issues a suspend command it will cause the instance to enter an ERROR state. Nova does not clean up an instance in this state correctly upon deletion. An attacker can use this to launch a denial of service attack. Only setups using the Nova VMware driver are affected by this flaw.

Juno (development branch) fix: https://review.openstack.org/94281/

Icehouse fix: https://review.openstack.org/109624/

Notes: This fix will be included in the Juno release 2014.2.0 and in the upcoming 2014.1.3 release.
