Two vulnerabilities have been reported in multiple VMware products, which can be exploited by malicious, local users to potentially gain escalated privileges, and by malicious people to compromise a vulnerable system.
1) An error related to the unsafe loading of libraries exists in the VMware Tools package for Windows. This can be exploited to execute arbitrary code on a guest system by tricking a user into clicking a file placed on a network share.
2) An error in the VMware Tools package for Windows can be exploited to potentially gain escalated privileges by placing a malicious executable in a certain location inside a guest operating system.
NOTE: This vulnerability cannot be exploited without administrative privileges on recent Windows versions (e.g. Windows XP and Windows Vista).
The vulnerabilities are reported in the following products and versions:
* VMware ESXi versions 3.5 and 4.0
* VMware ESX Server versions 2.5.5, 3.0.3, 3.5, and 4.0
* VMware Server 2.x
Solution: Apply patches and update VMware Tools in guest operating systems. Please see the vendor's advisory for more information.
