An updated rhev-hypervisor6 package that fixes two security issues isnow available.The Red Hat Security Response Team has rated this update as havingImportant security impact. Common Vulnerability Scoring System (CVSS) basescores, which give detailed severity ratings, are available for eachvulnerability from the CVE links in the References section.
The rhev-hypervisor6 package provides a Red Hat Enterprise VirtualizationHypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisoris a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includeseverything necessary to run and manage virtual machines: a subset of theRed Hat Enterprise Linux operating environment and the Red Hat EnterpriseVirtualization Agent.OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)and Transport Layer Security (TLS v1) protocols, as well as afull-strength, general purpose cryptography library.Note: Red Hat Enterprise Virtualization Hypervisor is only available forthe Intel 64 and AMD64 architectures with virtualization extensions.It was found that OpenSSL clients and servers could be forced, via aspecially crafted handshake packet, to use weak keying material forcommunication. A man-in-the-middle attacker could use this flaw to decryptand 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 beusing a vulnerable version of OpenSSL; the server must be using OpenSSLversion 1.0.1 and above, and the client must be using any version ofOpenSSL. For more information about this flaw, refer to:https://access.redhat.com/site/articles/904433A flaw was found in the way the handle_rx() function handled large networkpackets when mergeable buffers were disabled. A privileged guest user coulduse 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 withthe privileges of the QEMU process. (CVE-2014-0077)Red Hat would like to thank the OpenSSL project for reportingCVE-2014-0224. Upstream acknowledges KIKUCHI Masashi of Lepidum as theoriginal reporter of CVE-2014-0224. The CVE-2014-0077 issue was discoveredby Michael S. Tsirkin of Red Hat.This updated package provides updated components that include fixes forvarious security issues. These issues have no security impact on Red HatEnterprise Virtualization Hypervisor itself, however. The security fixesincluded 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, andCVE-2014-3470 (openssl issues)Users of the Red Hat Enterprise Virtualization Hypervisor are advised toupgrade to this updated package, which corrects these issues.
