RedHat: RHSA-2018-2274:01 Moderate: Red Hat Ceph Storage 2.5 security,
Summary
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 log 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)
