Security Advisory Important: rhev-3.1.0 vdsm security, bug fix, and enhancement update

Advisory: RHSA-2012:1508-1
Type: Security Advisory
Severity: Important
Issued on: 2012-12-04
Last updated on: 2012-12-04
Affected Products: Red Hat Enterprise Virtualization 3
CVEs ( CVE-2012-0860


Updated vdsm packages are now available for Red Hat Enterprise Linux 6.3.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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. (CVE-2012-0860)

A flaw was found in the way Red Hat Enterprise Linux and 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. (CVE-2012-0861)

The CVE-2012-0860 and CVE-2012-0861 issues were discovered by Red Hat.

In addition to resolving the above security issues these updated VDSM
packages fix various bugs, and add various enhancements.

Documentation for these bug fixes and enhancements is available in the
Technical Notes:

All users who require VDSM are advised to install these updated packages
which resolve these security issues, fix these bugs, and add these


Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
