RHSA-2018:2261: Moderate: Red Hat Ceph Storage 2.5 security, enhancement, and bug fix update

First published: Wed Jul 25 2018(Updated: )

Red Hat Ceph Storage is a scalable, open, software-defined storage platform<br>that combines the most stable version of the Ceph storage system with a<br>Ceph management platform, deployment utilities, and support services.<br>Security Fix(es):<br><li> ceph: cephx protocol is vulnerable to replay attack (CVE-2018-1128)</li> <li> ceph: cephx uses weak signatures (CVE-2018-1129)</li> <li> ceph: ceph-mon does not perform authorization on OSD pool ops (CVE-2018-10861)</li> For more details about the security issue(s), including the impact, a CVSS<br>score and other related information refer to the CVE page(s) listed in the Reference section.<br>Enhancement(s):<br><li> Ceph OSDs now logs when they shutdown due to disk operations timing out by default. (BZ#1568897)</li> <li> 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)</li> <li> The 'ceph-osdomap-tool' now has a 'compact' command to perform offline compaction on an OSD's 'omap' directory. (BZ#1574231)</li> <li> 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)</li> <li> 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)</li> Bug Fix(es):<br>These updated ceph packages include numerous bug fixes. Space precludes<br>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:<br><a href="https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2.5/html/release_notes/bug_fixes" target="_blank">https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2.5/html/release_notes/bug_fixes</a>
