Ubuntu Security Notice 3451-1 - It was discovered that OpenStack Swift incorrectly handled tempurls. A remote authenticated user in possession of a tempurl key authorized for PUT could retrieve other objects in the same Swift account. Romain Le Disez and Arjan Persson discovered that OpenStack Swift incorrectly closed client connections. A remote attacker could possibly use this issue to consume resources, resulting in a denial of service. Various other issues were also addressed.
70e90fd9f9d13513b72ce23eb9a5afc5589f7b785f6e14f8d84470b767224214Red Hat Security Advisory 2015-1895-01 - OpenStack Object Storage provides object storage in virtual containers, which allows users to store and retrieve files. The service's distributed architecture supports horizontal scaling; redundancy as failure-proofing is provided through software-based data replication. Because Object Storage supports asynchronous eventual consistency replication, it is well suited to deployment in multiple data centers. A flaw was found in the OpenStack Object storage service tempurls. An attacker in possession of a tempurl key with PUT permissions may be able to gain read access to other objects in the same project.
