VMware Security Advisory:- VMSA-2012-0015

This is the second of three. This one concerns VMware’s hosted products and the OVF Tool


Synopsis:   VMware Hosted Products and OVF Tool address security issues
Issue date: 2012-11-08
Updated on: 2012-11-08 (initial advisory)
CVE number: CVE-2012-5458, CVE-2012-5459 and CVE-2012-3569

1. Summary

VMware Hosted products and OVFTool patches address several security issues.

2. Relevant releases

  • OVF Tool 2.1
  • Workstation 8.0.4
  • Player 4.0.4

3. Problem Description

a. VMware Workstation and Player Weak permissions on process threads vulnerability.

Certain processes when created have weak security permissions assigned. It is possible to commandeer these process threads, which could result in Elevation of Privilege in the context of the host.

VMware would like to thank Derek Soeder of Cylance, Inc. for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-5458 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
vCenter any Windows not affected
Workstation 9.x any not affected
Workstation 8.x Windows 8.0.5
Workstation 8.x Linux not affected
Player 5.x any not affected
Player 4.x Windows 4.0.5 or later
Player 4.x Linux not affected
Fusion any Mac not affected
ESXi any ESXi not affected
ESX any ESX not affected

b. VMware Workstation and Player DLL binary planting vulnerability.

Workstation and Player have a binary planting vulnerability. An attacker who can write their malicious executable to a system folder on the host, may be able to run code under certain circumstances.

VMware would like to thank Derek Soeder of Cylance, Inc. for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-5459 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
vCenter any Windows not affected
Workstation 9.x any not affected
Workstation 8.x Windows 8.0.5
Workstation 8.x Linux not affected
Player 5.x any not affected
Player 4.x Windows 4.0.5 or later
Player 4.x Linux not affected
Fusion any Mac not affected
ESXi any ESXi not affected
ESX any ESX not affected

c. VMware OVF Tool format string vulnerability.

The OVFTool has a format string vulnerability. Exploitation of this issue may lead to code execution. In order to exploit the issue, the attacker would need to trick the user into loading their malicious OVF file.

It is recommended that only OVF files from trusted sources should be used.

VMware would like to thank Jeremy Brown of Microsoft for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-3569 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
vCenter any Windows not affected
OVF Tool 3.x any not affected
OVF Tool 2.1 Windows OVF Tool 3.0.1
OVF Tool 2.1 Linux/Mac not affected
OVF Tool 2.0 any not affected
Workstation 9.x any not affected
Workstation 8.x Windows 8.0.5
Workstation 8.x Linux not affected
Player 5.x any not affected
Player 4.x Windows 4.0.5 or later
Player 4.x Linux not affected
Fusion any Mac not affected
ESXi any ESXi not affected
ESX any ESX not affected

Note: Workstation, Player and the vSphere Web Client (part of vCenter Server) use the OVF Tool to load OVF files. Other products, including vCenter Server (except vSPhere Web Client), ESX, and vCloud Director do not use the OVF Tool to parse OVF files.
