CVE-2016-0738

Status Candidate

Overview

OpenStack Object Storage (Swift) before 2.3.1 (Kilo), 2.4.x, and 2.5.x before 2.5.1 (Liberty) do not properly close server connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.

Ubuntu Security Notice USN-3451-1

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.

Red Hat Security Advisory 2016-0328-01 - 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 multiple data-center deployment. A memory-leak issue was found in OpenStack Object Storage, in the proxy-to-server connection. An OpenStack-authenticated attacker could remotely trigger this flaw to cause denial of service through excess memory consumption.
