Summary: An updated rhev-hypervisor6 package that fixes multiple security issues 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. 2. Relevant releases/architectures: RHEV Hypervisor for RHEL-6 - noarch 3. Description: The rhev-hypervisor6 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. Upgrade Note: If you upgrade Red Hat Enterprise Virtualization Hypervisor 6.4 to version 6.5 through the 3.3 Manager administration portal, configuration of the previous system appears to be lost when reported in the TUI. However, this is an issue in the TUI itself, not in the upgrade process; the configuration of the system is not affected. A flaw was found in the way NSS handled invalid handshake packets. A remote attacker could use this flaw to cause a TLS/SSL client using NSS to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2013-5605) A flaw was found in the way OpenSSL determined which hashing algorithm to use when TLS protocol version 1.2 was enabled. This could possibly cause OpenSSL to use an incorrect hashing algorithm, leading to a crash of an application using the library. (CVE-2013-6449) A NULL pointer dereference flaw was found in the way OpenSSL handled TLS/SSL protocol handshake packets. A specially crafted handshake packet could cause a TLS/SSL client using OpenSSL to crash. (CVE-2013-4353) It was discovered that NSS did not reject certificates with incompatible key usage constraints when validating them while the verifyLog feature was enabled. An application using the NSS certificate validation API could accept an invalid certificate. (CVE-2013-5606) Red Hat would like to thank the Mozilla project for reporting CVE-2013-5606. Upstream acknowledges Camilo Viecco as the original reporter of CVE-2013-5606. 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-2013-6462 (libXfont issue) CVE-2013-6629, and CVE-2013-6630 (libjpeg-turbo issues) CVE-2013-1739, CVE-2013-1741, and CVE-2013-5607 (nss, nspr issues) CVE-2013-6450 (openssl issue) CVE-2013-6425 (pixman issue) Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which corrects these issues. 4. Solution: This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 To upgrade Hypervisors in Red Hat Enterprise Virtualization environments using the disk image provided by this package, refer to: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Hypervisor_Deployment_Guide/chap-Deployment_Guide-Upgrading_Red_Hat_Enterprise_Virtualization_Hypervisors.html 5.
