An authenticated attacker could launch a denial of service attack by sending null or specially crafted POST object requests. (CVE-2016-8626)\n\nBug Fix(es):\n\n* Dynamic Large Objects (DLOs) containing zero-length segments could cause the GET requests to enter an infinite loop or to fail depending on the position of the zero-length segment in an object, causing Ceph Object Gateway nodes to consume 100% of CPU. This bug has been fixed, and the GET requests succeed as expected in described situation. (BZ#1380196)\n\nEnhancement(s):\n\n* This update adds the \"apply-layout-settings\" command to the ceph-objectstore-tool utility. The new command enables users to perform collection splitting offline on OSD nodes in cases when doing it online would cause too large an impact. (BZ#1367441)\n\n* With this update, it is possible to change the maximum number shards per bucket. This is especially useful when bucket sharding was not configured correctly. (BZ#1378995)\n\nAll users of Red Hat Ceph Storage are advised to upgrade to these updated\npackages.",
