Summary
Red Hat Security Advisory: rhev-hypervisor security and bug fix update

Notes

Topic
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.
Details
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's QXL graphics card driver. A privileged guest user could use this flaw to cause the host to dereference an invalid pointer, causing the guest to crash (denial of service) or, possibly, resulting in the privileged guest user escalating their privileges on the host. (CVE-2010-0428) It was found that the libspice component of QEMU-KVM on the host could be forced to perform certain memory management operations on memory addresses controlled by a guest. A privileged guest user could use this flaw to crash the guest (denial of service) or, possibly, escalate their privileges on the host. (CVE-2010-0429) It was found that QEMU-KVM on the host did not validate all pointers provided from a guest system's QXL graphics card driver. A privileged guest user could use this flaw to cause the host to dereference an invalid pointer, causing the guest to crash (denial of service) or, possibly, resulting in the privileged guest user escalating their privileges on the host. (CVE-2010-0431) A flaw was found in QEMU-KVM, allowing the guest some control over the index used to access the callback array during sub-page MMIO initialization. A privileged guest user could use this flaw to crash the guest (denial of service) or, possibly, escalate their privileges on the host. (CVE-2010-2784) A NULL pointer dereference flaw was found when Red Hat Enterprise Virtualization Hypervisor was run on a system that has a processor with the Intel VT-x extension enabled. A privileged guest user could use this flaw to trick the host into emulating a certain instruction, which could crash the host (denial of service). (CVE-2010-0435) 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 packages provide updated components that include fixes for security issues; however, these issues have no security impact for Red Hat Enterprise Virtualization Hypervisor. These fixes are for avahi issues CVE-2009-0758 and CVE-2010-2244; freetype issues CVE-2010-1797, CVE-2010-2498, CVE-2010-2499, CVE-2010-2500, CVE-2010-2519, CVE-2010-2527, and CVE-2010-2541; kernel issues CVE-2010-1084, CVE-2010-2066, CVE-2010-2070, CVE-2010-2226, CVE-2010-2248, CVE-2010-2521, and CVE-2010-2524; and openldap issues CVE-2010-0211 and CVE-2010-0212. These updated rhev-hypervisor packages also fix two bugs. Documentation for these bug fixes will be available shortly from http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization_for_Servers/2.2/html/Technical_Notes/index.html As Red Hat Enterprise Virtualization Hypervisor is based on KVM, the bug fixes from the KVM update RHSA-2010:0627 have been included in this update. Also included are the bug fixes from the VDSM update RHSA-2010:0628. KVM: https://rhn.redhat.com/errata/RHSA-2010-0627.html VDSM: https://rhn.redhat.com/errata/RHSA-2010-0628.html Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to these updated rhev-hypervisor packages, which resolve these issues.
