Denial of service via network, Disclosure of system information, Disclosure of user information|
Fix Available: Yes Vendor Confirmed: Yes |
Several vulnerabilities were reported in Red Hat Enterprise Virtualization Manager. A remote authenticated user can cause denial of service conditions on the target system. A local user can access certain files on the target system.|
A remote authenticated user that can live-migrate a disk between storage domains can bypas the snapshot creation permission check and deny service [CVE-2015-0237].
The Red Hat Enterprise Visualization Engineering team reported this vulnerability.
A local user can exploit a directory permissions flaw on a directory shared between the ovirt-engine-dwhd service and a plug-in used during the service's startup to access potentially sensitive information in files in the directory [CVE-2015-0257].
Yedidyah Bar David of the Red Hat Enterprise Virtualization team reported this vulnerability.
A remote authenticated user can cause denial of service conditions on the target system.|
A local user can access certain files on the target system.
The vendor has issued a fix (3.5.1).|

RHEV-M 3.5 - noarch
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.
The Manager is a JBoss Application Server application that provides several
interfaces through which the virtual environment can be accessed and
interacted with, including an Administration Portal, a User Portal, and a
Representational State Transfer (REST) Application Programming Interface
It was discovered that the permissions to allow or deny snapshot creation
were ignored during live storage migration of a VM's disk between storage
domains. An attacker able to live migrate a disk between storage domains
could use this flaw to cause a denial of service. (CVE-2015-0237)
It was discovered that a directory shared between the ovirt-engine-dwhd
service and a plug-in used during the service's startup had incorrect
permissions. A local user could use this flaw to access files in this
directory, which could potentially contain sensitive information.
The CVE-2015-0237 issue was discovered by Red Hat Enterprise Visualization
Engineering, and the CVE-2015-0257 issue was discovered by Yedidyah Bar
David of the Red Hat Enterprise Virtualization team.
These updated Red Hat Enterprise Virtualization Manager packages also
include numerous bug fixes and various enhancements. Space precludes
documenting all of these changes in this advisory. Users are directed to
the Red Hat Enterprise Virtualization 3.5 Technical Notes, linked to in the
References, for information on the most significant of these changes.
All Red Hat Enterprise Virtualization Manager users are advised to upgrade
