This update for openstack-keystone, openstack-nova, and openstack-swift fixes the following issues:

• Fix hybrid backend from keystone v3 (bsc#967356)
• Fix cleanup when block migration fails (bsc#960015)
• Avoid host data leak (bsc#960601, CVE-2015-7548)
• Fix init script for openstack-swift-object-expirer
• Mark backend_argument as secret (bsc#929628, CVE-2015-3646)

George Shuklin discovered that OpenStack Nova incorrectly handled the migration process. A remote authenticated user could use this issue to consume resources, resulting in a denial of service. (CVE-2015-3241)

George Shuklin and Tushar Patil discovered that OpenStack Nova incorrectly handled deleting instances. A remote authenticated user could use this issue to consume disk resources, resulting in a denial of service. (CVE-2015-3280)

It was discovered that OpenStack Nova incorrectly limited qemu-img calls. A remote authenticated user could use this issue to consume resources, resulting in a denial of service. (CVE-2015-5162)

Matthew Booth discovered that OpenStack Nova incorrectly handled snapshots. A remote authenticated user could use this issue to read arbitrary files. (CVE-2015-7548)

Sreekumar S. and Suntao discovered that OpenStack Nova incorrectly applied security group changes. A remote attacker could possibly use this issue to bypass intended restriction changes by leveraging an instance that was running when the change was made. (CVE-2015-7713)

Matt Riedemann discovered that OpenStack Nova incorrectly handled logging. A local attacker could possibly use this issue to obtain sensitive information from log files. (CVE-2015-8749)

Matthew Booth discovered that OpenStack Nova incorrectly handled certain qcow2 headers. A remote authenticated user could possibly use this issue to read arbitrary files. (CVE-2016-2140)
