Denial Of Service (DoS)

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) A memory-leak issue was found in OpenStack Object Storage (swift), in the client-to-proxy connection. An OpenStack-authenticated attacker could remotely trigger this flaw to cause denial of service through excess memory consumption. (CVE-2016-0737) Red Hat would like to thank the OpenStack project for reporting these issues. Upstream acknowledges Romain Le Disez from OVH and –rjan 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.
