Synopsis

The remote Red Hat host is missing one or more security updates for rhev-hypervisor6.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2012:1200 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.

Multiple errors in glibc's formatted printing functionality could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort.
(CVE-2012-3404, CVE-2012-3405, CVE-2012-3406)

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-2012-3817 (bind issue)

CVE-2012-3571 and CVE-2012-3954 (dhcp issues)

CVE-2011-1078 and CVE-2012-2383 (kernel issues)

CVE-2012-1013 and CVE-2012-1015 (krb5 issues)

CVE-2012-0441 (nss issue)

CVE-2012-2668 (openldap issue)

CVE-2012-2337 (sudo issue)

Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes 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 these issues 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-2012:1200.
