CVE-2015-3241

OpenStack Compute (nova) 2015.1 through 2015.1.1, 2014.2.3, and earlier does not stop the migration process when the instance is deleted, which allows remote authenticated users to cause a denial of service (disk, network, and other resource consumption) by resizing and then deleting an instance.

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)
