"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 7.

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)

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 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."
