RHEL 7 : Red Hat Ceph Storage 2.1 (RHSA-2016:2954)

high Nessus Plugin ID 110332

Synopsis

The remote Red Hat host is missing a security update for Red Hat Ceph Storage 2.1.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2954 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):

* A flaw was found in the way Ceph Object Gateway would process cross-origin HTTP requests if the CORS policy was set to allow origin on a bucket. A remote unauthenticated attacker could use this flaw to cause denial of service by sending a specially-crafted cross-origin HTTP request. (CVE-2016-9579)

Bug Fix(es):

* Due to a bug in the underlying source code, OSD nodes sometimes looped through the entire placement group, not only the requested segment, during the scrubbing process. Consequently, in some cases, the OSD nodes reached the 'suicide timeout' and terminated. This bug has been fixed, and OSD nodes no longer terminate due to the described problem. (BZ#1394007)

* Due to changes in encoding of the OSD map in the ceph package version 10.2.2, upgrading from Red Hat Ceph Storage 1.3 to 2.0 sometimes led to serious performance issues on large clusters that contain hundreds of OSDs. With this update, the underlying source code has been improved, and upgrading from 1.3 to 2.0 works as expected. (BZ#1402185)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL Red Hat Ceph Storage 2.1 package based on the guidance in RHSA-2016:2954.
