  script_set_attribute(attribute:"description", value:
"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2018:2261 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform
    that combines the most stable version of the Ceph storage system with a
    Ceph management platform, deployment utilities, and support services.

    Security Fix(es):

    * ceph: cephx protocol is vulnerable to replay attack (CVE-2018-1128)

    * ceph: cephx uses weak signatures (CVE-2018-1129)

    * ceph: ceph-mon does not perform authorization on OSD pool ops (CVE-2018-10861)

    For more details about the security issue(s), including the impact, a CVSS
    score and other related information refer to the CVE page(s) listed in the Reference section.

    Enhancement(s):

    * Ceph OSDs now logs when they shutdown due to disk operations timing out by default. (BZ#1568897)

    * The `radosgw-admin orphans find` command can inadvertently remove data objects still in use, if followed
    by another operation, such as, a `rados rm` command. Users are now warned before attempting to produce
    lists of potentially orphaned objects. (BZ#1573656)

    * The 'ceph-osdomap-tool' now has a 'compact' command to perform offline compaction on an OSD's 'omap'
    directory. (BZ#1574231)

    * For S3 and Swift protocols, an option to list buckets/containers in natural (partial) order has been
    added. Listing containers in sorted order is canonical in both protocols, but is costly, and not required
    by some client applications. The performance and workload cost of S3 and Swift bucket/container listings
    is reduced for sharded buckets/containers when the `allow_unordered` extension is used. (BZ#1595374)

    * An asynchronous mechanism for executing the Ceph Object Gateway garbage collection using the `librados`
    APIs has been introduced. The original garbage collection mechanism serialized all processing, and lagged
    behind applications in specific workloads. Garbage collection performance has been significantly improved,
    and can be tuned to specific site requirements. (BZ#1595383)

    Bug Fix(es):

    These updated ceph packages include numerous bug fixes. Space precludes
    documenting all of these changes in this advisory. Users are directed to the Red Hat Ceph Storage 2.5
    Release Notes for information on the most significant bug fixes for this release:

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
