"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2014:0367 advisory.

    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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
