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.
