Bug Fix Advisory rhev-hypervisor bugfix update

Advisory: RHBA-2012:0015-2
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2012-01-11
Last updated on: 2012-01-17
Affected Products: Red Hat Enterprise Virtualization

Details

An updated rhev-hypervisor package that fixes various bugs is now available.

The rhev-hypervisor 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.

This updated package provides updated components that include fixes for
numerous 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-2011-4862 (a krb5 issue)

CVE-2011-1020, CVE-2011-3637, CVE-2011-4077, CVE-2011-4132, CVE-2011-4324,
CVE-2011-4325, CVE-2011-4330, and CVE-2011-4348 (kernel issues)

This update also fixes the following bug:

* The /etc/resolv.conf file was being overwritten every time a change was made
to networking. The statement PEERDNS="no" is now added to all interface
configuration (ifcfg*) files created by the hypervisor. This prevents the
incorrect overwriting of the /etc/resolv.conf file (BZ#768021).

This errata includes fixes included in kernel errata RHSA-2012:0007.

Users of Red Hat Enterprise Virtualization Hypervisor should upgrade to this
updated package, which fixes these bugs.
