Red Hat Storage is software-only, scale-out storage that provides flexible and affordable unstructured data storage for an enterprise. GlusterFS, a key building block of Red Hat Storage, is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnections into one large, parallel network file system.
A denial of service flaw was found in the way Python's SSL module implementation performed matching of certain certificate names. A remote attacker able to obtain a valid certificate that contained multiple wildcard characters could use this flaw to issue a request to validate such a certificate, resulting in excessive consumption of CPU. (CVE-2013-2099)
This issue was discovered by Florian Weimer of Red Hat Product Security.
This update also fixes several bugs and adds an enhancement. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Storage 2.1 Technical Notes, linked to in the References section, for information on the most significant of these changes.
With this update, a migration script 'migrate-rhs-classic-to-rhsm', that applies to both Red Hat Storage Server and Red Hat Storage Console is provided, that enables you to have the system prepared for upgrade from the latest release of RHS 2.x to RHS 3.0. From the Red Hat Storage 3.0 release onwards, there will be a significant change made in the subscription and delivery mechanism from the previous Red Hat Network Classic to the new Red Hat Subscription Manager, and this script assists in the smooth migration.
Users of Red Hat Storage are advised to upgrade to these updated packages, which correct these issues and add these enhancements.
Note: After upgrading, it is recommend that you refer to the Knowledge Base articles linked to in the References section which outlines an issue with rebalance and file creation error that has been identified by Red Hat. This issue will be fixed by a subsequent update.
