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.
