VMware Security Advisory:- VMSA-2012-0004

Just three advisories this week,  and this is one for those that are running VMware View.

Synopsis: VMware View privilege escalation and cross-site scripting
Issue date: 2012-03-15
Updated on: 2012-03-15 (initial advisory)
CVE numbers: CVE-2012-1508, CVE-2012-1509, CVE-2012-1510, CVE-2012-1511

1. Summary

VMware View addresses privilege escalation and cross-site scripting issues.

2. Relevant releases

View 4.6.0 and older.

3. Problem Description

a. VMware Virtual Desktop Display Driver Privilege Escalation

The VMware XPDM and WDDM display drivers contain buffer overflow vulnerabilities and the XPDM display driver does not properly check for NULL pointers. Exploitation of these issues may lead to local privilege escalation on View virtual desktops.

VMware would like to thank Tarjei Mandt for reporting theses issues to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2012-1509 (XPDM buffer overrun), CVE-2012-1510 (WDDM buffer overrun) and CVE-2012-1508 (XPDM null pointer dereference) to these issues.

Column 4 of the following table lists the action required to remediate the vulnerability in each release, if a solution is available.

VMware Product* Product Version Running On Replace with/Apply Patch **
View 5.0 Windows not affected
View 4.6 Windows View 4.6.1
View 4.0 Windows affected, no patch planned

* Other affected products are documented in VMSA-2012-0005; this advisory is exclusively for View.

** Notes on updating VMware Virtual Agents:

In order to remediate the problem, VMware View Agents must be updated in any pre-existing virtual desktops. The XPDM and WDDM drivers are part of the View Agent.

View Agents that have moved to View 5.0 from a lower View version are affected if their View Agent was not updated after the move.

b. View Manager Portal Cross-site Scripting

A cross-site scripting vulnerability in View Manager Portal may allow a remote attacker to run scripts in the victim’s browser. The attacker can trigger this vulnerability by supplying a crafted URL
to the victim and convincing them to click on the link.

VMware would like to thank Jeremy Conway for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1511 to this issue.

Column 4 of the following table lists the action required to remediate the vulnerability in each release, if a solution is
available.

VMware Product Product Version Running On Replace with/Apply Patch
View 5.0 Windows not affected
View 4.6 Windows View 4.6.1
View 4.0 Windows affected, no patch planned
