NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2010-0622.NASL description Updated rhev-hypervisor packages that fix multiple security issues and two bugs are now available. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The rhev-hypervisor package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. It was found that the libspice component of QEMU-KVM on the host did not validate all pointers provided from a guest system last seen 2020-06-01 modified 2020-06-02 plugin id 79276 published 2014-11-17 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/79276 title RHEL 5 : rhev-hypervisor (RHSA-2010:0622) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2010-0628.NASL 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.
