Published: 2008-09-26 12:12:58
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

Technical Details:
An input validation error is present in the Windows-based VMware HGFS.sys driver. Exploitation of this flaw might result in arbitrary code execution on the guest system by an unprivileged guest user. The HGFS.sys driver is present in the guest operating system if the VMware Tools Linux Distribution Package is loaded on Windows based Guest OS.

The host is installed with VMWare product(s) that are vulnerable to local privilege escalation vulnerability.

Affected Versions:
VMware Player 1.x - before 1.0.6 build 80404 on Linux VMware Server 1.x - before 1.0.5 build 80187 on Linux VMware Workstation 5.x - before 5.5.6 build 80404 on Linux

Upgrade VMware Product(s) to below version, VMware Player 1.0.6 build 80404 or later VMware Server 1.0.5 build 80187 or later VMware Workstation 5.5.6 build 80404 or later.

Successful exploitation could result in guest OS users to modify arbitrary memory locations in guest kernel memory and gain privileges. Issue still exists even if the host has HGFS disabled and has no shared folders.

Detection Type:

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
