Synopsis

The remote Red Hat host is missing a security update for vdsm22.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2010:0628 advisory.

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.

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 vdsm22 package based on the guidance in RHSA-2010:0628.
