Summary
Red Hat Security Advisory: rhev-hypervisor5 security and bug fix update

Notes

Topic
An updated rhev-hypervisor5 package that fixes several security issues and various bugs is 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-hypervisor5 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 heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-0029) A divide-by-zero flaw was found in the Linux kernel's igmp_heard_query() function. An attacker able to send certain IGMP (Internet Group Management Protocol) packets to a target system could use this flaw to cause a denial of service. (CVE-2012-0207) A double free flaw was discovered in the policy checking code in OpenSSL. A remote attacker could use this flaw to crash an application that uses OpenSSL by providing an X.509 certificate that has specially-crafted policy extension data. (CVE-2011-4109) An information leak flaw was found in the SSL 3.0 protocol implementation in OpenSSL. Incorrect initialization of SSL record padding bytes could cause an SSL client or server to send a limited amount of possibly sensitive data to its SSL peer via the encrypted connection. (CVE-2011-4576) It was discovered that OpenSSL did not limit the number of TLS/SSL handshake restarts required to support Server Gated Cryptography. A remote attacker could use this flaw to make a TLS/SSL server using OpenSSL consume an excessive amount of CPU by continuously restarting the handshake. (CVE-2011-4619) Red Hat would like to thank Nicolae Mogoreanu for reporting CVE-2012-0029, and Simon McVittie for reporting CVE-2012-0207. This updated package provides updated components that include fixes for various security issues. These issues have no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers: CVE-2006-1168 and CVE-2011-2716 (busybox issues) CVE-2009-5029, CVE-2009-5064, CVE-2010-0830 and CVE-2011-1089 (glibc issues) CVE-2011-1083, CVE-2011-3638, CVE-2011-4086, CVE-2011-4127 and CVE-2012-0028 (kernel issues) CVE-2011-1526 (krb5 issue) CVE-2011-4347 (kvm issue) CVE-2010-4008, CVE-2011-0216, CVE-2011-2834, CVE-2011-3905, CVE-2011-3919 and CVE-2011-1944 (libxml2 issues) CVE-2011-1749 (nfs-utils issue) CVE-2011-4108 (openssl issue) CVE-2011-0010 (sudo issue) CVE-2011-1675 and CVE-2011-1677 (util-linux issues) CVE-2010-0424 (vixie-cron issue) This updated rhev-hypervisor5 package fixes various bugs. Documentation of these changes will be available shortly in the Technical Notes document: https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization_for_Servers/2.2/html/Technical_Notes/index.html Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues.
