Summary
Red Hat Security Advisory: rhev-hypervisor6 security update

Notes

Topic
An updated rhev-hypervisor6 package that fixes two 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.
Details
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. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. (CVE-2014-0224) Note: In order to exploit this flaw, both the server and the client must be using a vulnerable version of OpenSSL; the server must be using OpenSSL version 1.0.1 and above, and the client must be using any version of OpenSSL. For more information about this flaw, refer to: https://access.redhat.com/site/articles/904433 A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0077) Red Hat would like to thank the OpenSSL project for reporting CVE-2014-0224. Upstream acknowledges KIKUCHI Masashi of Lepidum as the original reporter of CVE-2014-0224. The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red Hat. 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-2014-0015 and CVE-2014-0138 (curl issues) CVE-2014-2523 and CVE-2013-6383 (kernel issues) CVE-2014-0179 (libvirt issue) CVE-2010-5298, CVE-2014-0198, CVE-2014-0221, CVE-2014-0195, and CVE-2014-3470 (openssl issues) Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which corrects these issues.
