The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2177 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 References section.

    Bug Fix(es):

    * Previously, Ceph RADOS Gateway (RGW) instances in zones configured for multi-site replication would     crash if configured to disable sync (rgw_run_sync_thread = false). Therefor, multi-site replication     environments could not start dedicated non-replication RGW instances. With this update, the     rgw_run_sync_thread option can be used to configure RGW instances that will not participate in     replication even if their zone is replicated. (BZ#1552202)

    * Previously, when increasing max_mds from 1 to 2, if the Metadata Server (MDS) daemon was in the     starting/resolve state for a long period of time, then restarting the MDS daemon lead to assert. This     caused the Ceph File System (CephFS) to be in degraded state. With this update, increasing max_mds no     longer causes CephFS to be in degraded state. (BZ#1566016)

    * Previously, the transition to containerized Ceph left some ceph-disk unit files. The files were     harmless, but appeared as failing. With this update, executing the switch-from-non-containerized-to-     containerized-ceph-daemons.yml playbook disables the ceph-disk unit files too. (BZ#1577846)

    * Previously, the entries_behind_master metric output from the rbd mirror image status CLI tool did     not always reduce to zero under synthetic workloads. This could cause a false alarm that there is an issue     with RBD mirroring replications. With this update, the metric is now updated periodically without the need     for an explicit I/O flush in the workload. (BZ#1578509)

    * Previously, when using the pool create command with expected_num_objects, placement group (PG)     directories were not pre-created at pool creation time as expected, resulting in performance drops when     filestore splitting occurred. With this update, the expected_num_objects parameter is now passed through     to filestore correctly, and PG directories for the expected number of objects are pre-created at pool     creation time. (BZ#1579039)

    * Previously, internal RADOS Gateway (RGW) multi-site sync logic behaved incorrectly when attempting to     sync containers with S3 object versioning enabled. Objects in versioning-enabled containers would fail to     sync in some scenariosfor example, when using s3cmd sync to mirror a filesystem directory. With this     update, RGW multi-site replication logic has been corrected for the known failure cases. (BZ#1580497)

    * When restarting OSD daemons, the ceph-ansible restart script goes through all the daemons by listing     the units with systemctl list-units. Under certain circumstances, the output of the command contains extra     spaces, which caused parsing and restart to fail. With this update, the underlying code has been changed     to handle the extra space.

    * Previously, the Ceph RADOS Gateway (RGW) server treated negative byte-range object requests (bytes=0--     1) as invalid. Applications that expect the AWS behavior for negative or other invalid range requests saw     unexpected errors and could fail. With this update, a new option rgw_ignore_get_invalid_range has been     added to RGW. When rgw_ignore_get_invalid_range is set to true, the RGW behavior for invalid range     requests is backwards compatible with AWS.
