Synopsis

The remote Red Hat host is missing a security update for rhev-hypervisor6.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2013:1076 advisory.

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 included in this update address the following CVE numbers:

CVE-2013-2174 (curl issue)

CVE-2012-6548, CVE-2013-0914, CVE-2013-1848, CVE-2013-2128, CVE-2013-2634, CVE-2013-2635, CVE-2013-2852, CVE-2013-3222, CVE-2013-3224, CVE-2013-3225, and CVE-2013-3301 (kernel issues)

CVE-2002-2443 (krb5 issue)

CVE-2013-1950 (libtirpc issue)

Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization Hypervisor through the 3.2 Manager administration portal, the Host may appear with the status of Install Failed. If this happens, place the host into maintenance mode, then activate it again to get the host back to an Up state.

This update also contains the fixes from the following errata:

* ovirt-node: RHBA-2013:1077

Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which corrects these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL rhev-hypervisor6 package based on the guidance in RHSA-2013:1076.
