1. Summary:
Several critical security vulnerabilities have been addressed in the newest releases of VMware's hosted product line.
2. Relevant releases:
VMware Workstation 6.0.2 and earlier
VMware Workstation 5.5.4 and earlier
VMware Player 2.0.2 and earlier
VMware Player 1.0.4 and earlier
VMware ACE 2.0.2 and earlier
VMware ACE 1.0.2 and earlier

3. Problem description:
a. Host to guest shared folder (HGFS) traversal vulnerability
On Windows hosts, if you have configured a VMware host to guest shared folder (HGFS), it is possible for a program running in the guest to gain access to the host's file system and create or modify executable files in sensitive locations.
NOTE: VMware Server is not affected because it doesn't use host to guest shared folders. No versions of ESX Server, including ESX Server 3i, are affected by this vulnerability. Because ESX Server is based on a bare-metal hypervisor architecture and not a hosted architecture, and it doesn't include any shared folder abilities. Fusion and Linux based hosted products are unaffected.
VMware would like to thank CORE Security Technologies for working with us on this issue. This addresses advisory CORE-2007-0930.
The Common Vulnerabilities and exposures project (cve.mitre.org) has assigned the name CVE-2008-0923 to this issue.

b. Insecure named pipes
An internal security audit determined that a malicious Windows user could attain and exploit LocalSystem privileges by causing the authd process to connect to a named pipe that is opened and controlled by the malicious user.
The same internal security audit determined that a malicious Windows user could exploit an insecurely created named pipe object to escalate privileges or create a denial of service attack. In this situation, the malicious user could successfully impersonate authd and attain privileges under which Authd is executing.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2008-1361, CVE-2008-1362 to these issues.

e. VIX API default setting changed to a more secure default value
Workstation 6.0.2 allowed anonymous console access to the guest by means of the VIX API. This release, Workstation 6.0.3, disables this feature.
This means that the Eclipse Integrated Virtual Debugger and the Visual Studio Integrated Virtual Debugger will now prompt for user account credentials to access a guest.
