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.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3451-1 advisory.

    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.
    (CVE-2015-5223)

    Romain Le Disez and rjan 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.
    (CVE-2016-0737, CVE-2016-0738)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Security fix for CVE-2016-0738

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated openstack-swift packages that fix two security issues are now available for Red Hat Gluster Storage 3.1 update 2 in Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

OpenStack Object Storage (swift) provides object storage in virtual containers, which allows users to store and retrieve files (arbitrary data). 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 (swift), in the proxy-to-server connection. An OpenStack-authenticated attacker could remotely trigger this flaw to cause denial of service through excess memory consumption. (CVE-2016-0738)

Red Hat would like to thank the OpenStack project for reporting these issues. Upstream acknowledges Romain Le Disez from OVH and Orjan Persson from Kiliaro as the original reporters.

All users of openstack-swift are advised to upgrade to these updated packages, which correct these issues. After installing this update, the OpenStack Object Storage services will be restarted automatically.
