1. Summary:

Updated openstack-swift packages that fix two security issues are now
available for Red Hat Enterprise Linux OpenStack Platform 7.0.

Red Hat Product Security has rated this update as having Moderate 
security impact. A Common Vulnerability Scoring System (CVSS) base 
score, which gives a detailed severity rating, is available from the 
CVE link in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - noarch

3. Description:

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 Örjan 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.
