OpenStack Object Storage (Swift) before 2.3.0, when allow_version is configured, allows remote authenticated users to delete the latest version of an object by leveraging listing access to the x-versions-location container.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:1684 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 flaw was found in OpenStack Object Storage that could allow an     authenticated user to delete the most recent version of a versioned object     regardless of ownership. To exploit this flaw, an attacker must know the     name of the object and have listing access to the x-versions-location     container. (CVE-2015-1856)

    Red Hat would like to thank the OpenStack project for reporting this issue.
    Upstream acknowledges Clay Gerrard 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.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1846 advisory.

    Red Hat Gluster Storage is a software only scale-out storage solution that     provides flexible and affordable unstructured data storage. It unifies data     storage and infrastructure, increases performance, and improves     availability and manageability to meet enterprise-level storage challenges.

    Red Hat Gluster Storage's Unified File and Object Storage is built on     OpenStack's Object Storage (swift).

    A flaw was found in the metadata constraints in Red Hat Gluster Storage's     OpenStack Object Storage (swiftonfile). 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-2014-8177)

    This update also fixes numerous bugs and adds various enhancements. Space     precludes documenting all of these changes in this advisory. Users are     directed to the Red Hat Gluster Storage 3.1 Technical Notes, linked to in     the References section, for information on the most significant of these     changes.

    This advisory introduces the following new features:

    * Gdeploy is a tool which automates the process of creating, formatting,     and mounting bricks. When setting up a fresh cluster, gdeploy could be the     preferred choice of cluster set up, as manually executing numerous commands     can be error prone. The advantages of using gdeploy includes automated     brick creation, flexibility in choosing the drives to configure (sd, vd,     etc.), and flexibility in naming the logical volumes (LV) and volume groups     (VG). (BZ#1248899)

    * The gstatus command is now fully supported. The gstatus command provides     an easy-to-use, high-level view of the health of a trusted storage pool     with a single command. It gathers information about the health of a Red Hat     Gluster Storage trusted storage pool for distributed, replicated,     distributed-replicated, dispersed, and distributed-dispersed volumes.
    (BZ#1250453)

    * You can now recover a bad file detected by BitRot from a replicated     volume. The information about the bad file will be logged in the scrubber     log file located at /var/log/glusterfs/scrub.log. (BZ#1238171)

    * Two tailored tuned profiles are introduced to improve the performance for     specific Red Hat Gluster Storage workloads. They are: rhgs-sequential-io,     which improves performance of large files with sequential I/O workloads,     and rhgs-random-io, which improves performance of small files with random     I/O workloads (BZ# 1251360)

    All users of Red Hat Gluster Storage are advised to apply this update.
