Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated vdsm22 packages that fix one security issue and multiple bugs are now available for Red Hat Enterprise Linux 5.5.

The Red Hat Security Response Team 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.

VDSM is a management module that serves as a Red Hat Enterprise Virtualization Manager agent on Red Hat Enterprise Virtualization Hypervisor or Red Hat Enterprise Linux hosts.

Note: This update has been tested and is supported on Red Hat Enterprise Linux 5.5 (with all appropriate post-GA 5.5-specific updates).

A flaw was found in the way VDSM accepted SSL connections. An attacker could trigger this flaw by creating a crafted SSL connection to VDSM, preventing VDSM from accepting SSL connections from other users.
(CVE-2010-2811)

These updated vdsm22 packages also fix the following bugs :

* suspend-to-file hibernation failed for huge guests due to the migration and hibernation constant values being too short for huge guests. This update makes the timeouts proportional to guest RAM size, thus allowing suspension of huge guests in all cases except where storage is unbearably slow. (BZ#601275)

* under certain circumstances, restarting a VDSM that was being used as a Storage Pool Manager killed all system processes on the host.
With this update, stopping VDSM is ensured to kill only the processes that it started, and the VDSM SIGTERM handler is not run concurrently.
With these changes, all processes on the host are no longer killed when VDSM is restarted. (BZ#614849)

* when VDSM was requested to 'start in paused mode', it incorrectly reported virtual guest state as 'WaitForLaunch' instead of 'Paused', which led to the virtual guest being inaccessible from Red Hat Enterprise Virtualization Manager. With this update, VDSM reports such virtual guests as 'Paused', and users are able to connect to the virtual guest display. (BZ#616464)

Red Hat Enterprise Virtualization Manager 2.2 users with Red Hat Enterprise Linux hosts should install these updated packages, which resolve these issues. Alternatively, Red Hat Enterprise Virtualization Manager can install the new package automatically.

Solution

Update the affected vdsm22 and / or vdsm22-cli packages.
