Impact:
Security Bypass

Where:
Local system

Solution Status:
Vendor Patch

CVE reference:
CVE-2008-2098 (Secunia mirror)
CVE-2008-2099 (Secunia mirror)

Description:
Some vulnerabilities have been reported in multiple VMware products, which can be exploited by malicious, local users to bypass certain security restrictions.

1) A boundary error exists in the implementation of the Host Guest File System (HGFS). This can be exploited to cause a heap-based buffer overflow in the context of the "vmx" process on the host system.

Successful exploitation requires that shared folders are enabled and at least one folder is shared on the host (not by default).

2) An unspecified error in the Virtual Machine Communication Interface (VMCI) implementation can be exploited to execute arbitrary code in the context of the "vmx" process on the host system.

Successful exploitation requires that VMCI is enabled and that the VMware host is running on Windows.
