CVE-2012-0861

Status Candidate

Overview

The vds_installer in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when adding a host, uses the -k curl parameter when downloading deployUtil.py and vds_bootstrap.py, which prevents SSL certificates from being validated and allows remote attackers to execute arbitrary Python code via a man-in-the-middle attack.

Red Hat Security Advisory 2012-1506-01
Posted Dec 4, 2012

Red Hat Security Advisory 2012-1506-01 - Red Hat Enterprise Virtualization Manager is a visual tool for centrally managing collections of virtual servers running Red Hat Enterprise Linux and Microsoft Windows. This package also includes the Red Hat Enterprise Virtualization Manager API, a set of scriptable commands that give administrators the ability to perform queries and operations on Red Hat Enterprise Virtualization Manager. A flaw was found in the way Red Hat Enterprise Linux hosts were added to the Red Hat Enterprise Virtualization environment. The Python scripts needed to configure the host for Red Hat Enterprise Virtualization were stored in the "/tmp/" directory and could be pre-created by an attacker. A local, unprivileged user on the host to be added to the Red Hat Enterprise Virtualization environment could use this flaw to escalate their privileges. This update provides the Red Hat Enterprise Virtualization Manager part of the fix. The RHSA-2012:1508 VDSM update must also be installed to completely fix this issue.

Red Hat Security Advisory 2012-1508-01 - VDSM is a management module that serves as a Red Hat Enterprise Virtualization Manager agent on Red Hat Enterprise Virtualization Hypervisor or Red Hat Enterprise Linux 6.3 hosts. A flaw was found in the way Red Hat Enterprise Linux hosts were added to the Red Hat Enterprise Virtualization environment. The Python scripts needed to configure the host for Red Hat Enterprise Virtualization were stored in the "/tmp/" directory and could be pre-created by an attacker. A local, unprivileged user on the host to be added to the Red Hat Enterprise Virtualization environment could use this flaw to escalate their privileges. This update provides the VDSM part of the fix. The RHSA-2012:1506 Red Hat Enterprise Virtualization Manager update must also be installed to completely fix this issue.

Red Hat Security Advisory 2012-1505-01 - 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 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. A flaw was found in the way Red Hat Enterprise Virtualization Hypervisor hosts were added to the Red Hat Enterprise Virtualization environment. The Python scripts needed to configure the host for Red Hat Enterprise Virtualization were downloaded in an insecure way, that is, without properly validating SSL certificates during HTTPS connections. An attacker on the local network could use this flaw to conduct a man-in-the-middle attack, potentially gaining root access to the host being added to the Red Hat Enterprise Virtualization environment. This update provides the VDSM part of the fix. The RHSA-2012:1506 Red Hat Enterprise Virtualization Manager update must also be installed to completely fix this issue.
