Openstack glance: swift: s3: openstack glance: information disclosure of backend credentials via cached image request

A flaw was found in OpenStack Glance. Remote authenticated users can exploit this vulnerability by requesting a cached image when the single-tenant Swift or S3 store is in use. This action causes the system to report the location field, which can lead to the disclosure of the operator's backend credentials.

Openstack nova: information leak in libvirt lvm-backed instances

OpenStack Compute (Nova) Folsom before 2012.2.2 and Grizzly, when using libvirt and LVM backed instances, does not properly clear physical volume (PV) content when reallocating for instances, which allows attackers to obtain sensitive information by reading the memory of the previous logical volume (LV).

Packstack: packstack: arbitrary file overwrite via symlink attack

A flaw was found in PackStack. A local user could exploit a symlink attack on a temporary file with a predictable name in the `/tmp` directory. This vulnerability allows the local user to overwrite arbitrary files on the system, potentially leading to system compromise or data corruption.

Puppetlabs-cinder: packstack: openstack: puppetlabs-cinder: information disclosure of openstack administrative passwords due to world-readable configuration files.

A flaw was found in the `puppetlabs-cinder` module, as used in PackStack. This vulnerability is due to incorrect file permissions, specifically world-readable permissions, on the `cinder.conf` and `api-paste.ini` configuration files. A local user can exploit this by reading these files, which leads to the disclosure of OpenStack administrative passwords. This information disclosure could allow unauthorized access to sensitive OpenStack resources.

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

A flaw was found in OpenStack Keystone. This vulnerability allows remote authenticated users to bypass intended authorization restrictions. This occurs because OpenStack Keystone does not properly handle EC2 (Elastic Compute Cloud) tokens when a user's role has been removed from a tenant. An attacker can leverage a token associated with a removed user role to gain unauthorized access.

Openstack nova: vnc proxy can connect to the wrong vm

OpenStack Compute (Nova) Grizzly, Folsom (2012.2), and Essex (2012.1) allows remote authenticated users to gain access to a VM in opportunistic circumstances by using the VNC token for a deleted VM that was bound to the same VNC port.

OpenStack: Keystone extension of token validity through token chaining

OpenStack Keystone, as used in OpenStack Folsom 2012.2, does not properly implement token expiration, which allows remote authenticated users to bypass intended authorization restrictions by creating new tokens through token chaining. NOTE: this issue exists because of a CVE-2012-3426 regression.

openstack-nova: Boot from volume allows access to random volumes

The boot-from-volume feature in OpenStack Compute (Nova) Folsom and Essex, when using nova-volumes, allows remote authenticated users to boot from other users' volumes via a volume id in the block_device_mapping parameter.

bindings: Internal entity expansion in Python XML libraries inflicts DoS vulnerabilities

The XML libraries for Python 3.4, 3.3, 3.2, 3.1, 2.7, and 2.6, as used in OpenStack Keystone Essex, Folsom, and Grizzly; Compute (Nova) Essex and Folsom; Cinder Folsom; Django; and possibly other products allow remote attackers to cause a denial of service (resource consumption and crash) via an XML Entity Expansion (XEE) attack.

bindings: External entity expansion in Python XML libraries inflicts potential security flaws and DoS vulnerabilities

The XML libraries for Python 3.4, 3.3, 3.2, 3.1, 2.7, and 2.6, as used in OpenStack Keystone Essex and Folsom, Django, and possibly other products allow remote attackers to read arbitrary files via an XML external entity declaration in conjunction with an entity reference, aka an XML External Entity (XXE) attack.

Nova: DoS by allocating all Fixed IPs

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.

keystone: online validation of Keystone PKI tokens bypasses revocation check

OpenStack Keystone Folsom (2012.2) does not properly perform revocation checks for Keystone PKI tokens when done through a server, which allows remote attackers to bypass intended access restrictions via a revoked PKI token.

nova: insecure directory creation for signing

keystone/middleware/auth_token.py in OpenStack Nova Folsom, Grizzly, and Havana uses an insecure temporary directory for storing signing certificates, which allows local users to spoof servers by pre-creating this directory, which is reused by Nova, as demonstrated using /tmp/keystone-signing-nova on Fedora.

Nova: fails to verify image virtual size denial of service

OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by creating an image with a large virtual size that does not contain a large amount of data.

Swift: Unchecked user input in Swift XML responses

XML injection vulnerability in account/utils.py in OpenStack Swift Folsom, Grizzly, and Havana allows attackers to trigger invalid or spoofed Swift responses via an account name.

OpenStack: Swift Denial of Service using superfluous object tombstones

OpenStack Swift before 1.9.1 in Folsom, Grizzly, and Havana allows authenticated users to cause a denial of service ("superfluous" tombstone consumption and Swift cluster slowdown) via a DELETE request with a timestamp that is older than expected.

OpenStack: openstack-nova-compute console-log DoS

OpenStack Compute (Nova) Folsom, Grizzly, and earlier, when using Apache Qpid for the RPC backend, does not properly handle errors that occur during messaging, which allows remote attackers to cause a denial of service (connection pool consumption), as demonstrated using multiple requests that send long strings to an instance console and retrieving the console log.

Nova: Compressed disk image DoS

OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not properly verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) via a compressed QCOW2 image. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.

Nova: Incomplete fix for CVE-2013-2096

OpenStack Compute (Nova) Folsom, Grizzly, and Havana, when use_cow_images is set to False, does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by transferring an image with a large virtual size that does not contain a large amount of data from Glance. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.

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.
