(RHSA-2013:1076) Important: rhev-hypervisor6 security and bug fix update

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.

It was discovered that the fix for the CVE-2013-1619 issue released via
RHSA-2013:0636 introduced a regression in the way GnuTLS decrypted TLS/SSL
encrypted records when CBC-mode cipher suites were used. A remote attacker
could possibly use this flaw to crash a server or client application that
uses GnuTLS. (CVE-2013-2116)

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
