(RHSA-2011:1090) Moderate: rhev-hypervisor security and bug fix update

Description

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. A flaw was found that allowed napi_reuse_skb() to be called on VLAN (virtual LAN) packets. An attacker on the local network could trigger this flaw by sending specially-crafted packets to a target system, possibly causing a denial of service. (CVE-2011-1576) Red Hat would like to thank Ryan Sweat for reporting CVE-2011-1576. This updated package provides 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 bash issue CVE-2008-5374; curl issue CVE-2011-2192; kernel issues CVE-2010-4649, CVE-2011-0695, CVE-2011-0711, CVE-2011-1044, CVE-2011-1182, CVE-2011-1573, CVE-2011-1593, CVE-2011-1745, CVE-2011-1746, CVE-2011-1776, CVE-2011-1780, CVE-2011-1936, CVE-2011-2022, CVE-2011-2213, CVE-2011-2492, CVE-2011-2525, and CVE-2011-2689; libvirt issue CVE-2011-2511; and rsync issue CVE-2007-6200. This update also fixes several bugs. Documentation for these bug fixes will be available shortly from the Technical Notes document linked to in the References section. As Red Hat Enterprise Virtualization Hypervisor is based on KVM, the bug fixes from the KVM update RHBA-2011:1068 have been included in this update: https://rhn.redhat.com/errata/RHBA-2011-1068.html Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which resolves this issue and fixes the bugs noted in the Technical Notes.
