Red Hat: 2015:0836-01: openstack-swift: Moderate Advisory
Summary
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 flaw was found in the metadata constraints in OpenStack Object Storage
(swift). By adding metadata in several separate calls, a malicious user
could bypass the max_meta_count constraint, and store more metadata than
allowed by the configuration. (CVE-2014-7960)
All users of openstack-swift are advised to upgrade to these updated
packages, which correct this issue. After installing this update, the
OpenStack Object Storage services will be restarted automatically.
