RHEL 7 : Red Hat Ceph Storage 1.3.1 (RHSA-2015:2066)
Medium Nessus Plugin ID 87043
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionRed Hat Ceph Storage 1.3.1 that fixes one security issue, multiple bugs, and adds various enhancements is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Red Hat Ceph Storage is a massively scalable, open, software-defined storage platform that combines the most stable version of the Ceph storage system with a Ceph management platform, deployment tools, and support services.
A feature in Ceph Object Gateway (RGW) allows to return a specific HTTP header that contains the name of a bucket that was accessed. It was found that the returned HTTP headers were not sanitized. An unauthenticated attacker could use this flaw to craft HTTP headers in responses that would confuse the load balancer residing in front of RGW, potentially resulting in a denial of service. (CVE-2015-5245)
The ceph packages have been upgraded to upstream version 0.94.3 and the radosgw-agent packages have been upgraded to upstream version 1.2.3. The new versions provide a number of bug fixes and enhancements over the previous versions. (BZ#1238415)
This update also fixes the following bugs :
* This update fixes various bugs in the Ceph monitor nodes and the Ceph Object Storage Device (OSD) Daemons. (BZ#1219040, BZ#1223941, BZ#1265973)
* With this update, when using the Civetweb server, the Ceph Object Gateway no longer reports the full object size downloaded even though the download was aborted in the middle. (BZ#1235845)
* The Civetweb server now correctly displays the HTTP return code in the log files. (BZ#1245663)
* The Ceph Object Gateway now correctly assigns Access Control Lists (ACL) to new objects created during the copy operation. (BZ#1253766)
* Under certain circumstances, copying an object onto itself (for example, to change its metadata) produced a truncated object. The truncated object had correct metadata, including the original size, but the underlying RADOS object was smaller. Consequently, when a client attempted to fetch the object, it received less data than indicated by the Content-Length header, blocked for more, and eventually timed out. This bug has been fixed, and the object can now be read successfully in the aforementioned scenario. (BZ#1258618)
* The Ceph Object Gateway no longer requires the 'requiretty' setting to be disabled in the sudoers configuration for the root user.
* In certain scenarios, when all acting set Ceph Object Storage Device (OSD) Daemons for a placement group (PG) were restarted during the backfill process, the OSDs failed to peer the PG. Now, the OSDs peer the PGs as expected. (BZ#1223532)
In addition, this update adds the following enhancements :
* Administrators of the Ceph Object Gateway can now configure the maximum number of buckets for users by using the new 'rgw_user_max_buckets' option in the Ceph configuration file.
* The suicide timeout option is now configurable. The option ensures that poorly behaving OSDs self-terminate instead of running in degraded states and slowing traffic. (BZ#1210825)
* The rhcs-installer package provides a new Foreman-based installer.
This update adds the new rhcs-installer package to Red Hat Ceph Storage as a Technology Preview. (BZ#1213026, BZ#1213086, BZ#1220961)
