OpenStack Compute (Essex) 2012.1

Openstack nova: vnc proxy can connect to the wrong vm

The v1 API in OpenStack Glance Grizzly, Folsom (2012.2), and Essex (2012.1) allows remote authenticated users to delete arbitrary non-protected images via an image deletion request, a different vulnerability than CVE-2012-5482.

Directory traversal vulnerability in virt/disk/api.py in OpenStack Compute (Nova) Folsom (2012.2) and Essex (2012.1), when used over libvirt-based hypervisors, allows remote authenticated users to write arbitrary files to the disk image via a .. (dot dot) in the path attribute of a file element.

The v2 API in OpenStack Glance Grizzly, Folsom (2012.2), and Essex (2012.1) allows remote authenticated users to delete arbitrary non-protected images via an image deletion request. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-4573.

virt/disk/api.py in OpenStack Compute (Nova) Folsom (2012.2), Essex (2012.1), and Diablo (2011.3) allows remote authenticated users to overwrite arbitrary files via a symlink attack on a file in an image.

Openstack keystone: openstack keystone: authorization bypass via improper ec2 token handling

The (1) EC2 and (2) OS APIs in OpenStack Compute (Nova) Folsom (2012.2), Essex (2012.1), and Diablo (2011.3) do not properly check the protocol when security groups are created and the network protocol is not specified entirely in lowercase, which allows remote attackers to bypass intended access restrictions.

OpenStack Keystone, as used in OpenStack Folsom before folsom-rc1 and OpenStack Essex (2012.1), allows remote attackers to add an arbitrary user to an arbitrary tenant via a request to update the user's default tenant to the administrative API. NOTE: this identifier was originally incorrectly assigned to an open redirect issue, but the correct identifier for that issue is CVE-2012-3540.

OpenStack Compute (Nova) Grizzly, Folsom (2012.2), and Essex (2012.1) does not properly implement a quota for fixed IPs, which allows remote authenticated users to cause a denial of service (resource exhaustion and failure to spawn new instances) via a large number of calls to the addFixedIp function.

The Nova scheduler in OpenStack Compute (Nova) Folsom (2012.2) and Essex (2012.1), when DifferentHostFilter or SameHostFilter is enabled, allows remote authenticated users to cause a denial of service (excessive database lookup calls and server hang) via a request with many repeated IDs in the os:scheduler_hints section.

The v1 API in OpenStack Glance Essex (2012.1), Folsom (2012.2), and Grizzly, when using the single-tenant Swift or S3 store, reports the location field, which allows remote authenticated users to obtain the operator's backend credentials via a request for a cached image.
