RHSA-2014:0232 - Security Advisory

Topic

Updated openstack-swift packages that fix one security issue are now
available for Red Hat Enterprise Linux OpenStack Platform 4.0.

The Red Hat Security Response Team 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.

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 timing attack flaw was found in the way the swift TempURL middleware
responded to arbitrary TempURL requests. An attacker with knowledge of an
object's name could use this flaw to obtain a secret URL to this object,
which was intended to be publicly shared only with specific recipients, if
the object had the TempURL key set. Note that only setups using the TempURL
middleware were affected. (CVE-2014-0006)

Red Hat would like to thank the Openstack Project for reporting this issue.
Upstream acknowledges Samuel Merritt of SwiftStack as the original
reporter.

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.
