VMware Security Advisory
Advisory ID: VMSA-2008-0008
Synopsis: Updates to VMware Workstation, VMware Player,
VMware ACE, VMware Fusion resolve critical
security issues
Issue date: 2008-05-30
Updated on: 2008-05-30 (initial release of advisory)
CVE numbers: CVE-2008-2098 CVE-2008-2099
- -------------------------------------------------------------------
1. Summary:
Several critical security vulnerabilities have been addressed
in the newest releases of VMware's hosted product line.
2. Relevant releases:
VMware Workstation 6.0.3 and earlier,
VMware Player 2.0.3 and earlier,
VMware ACE 2.0.3 and earlier,
VMware Fusion 1.1.1 and earlier
NOTES: Users of VMware hosted products VMware Workstation 5.x,
VMware Player 1.x, and VMware ACE 1.x should note that
although they are not vulnerable to these issue, they
will reach their end of general support on 2008-11-09.
Customers should plan to upgrade to the latest version
of their respective products.
3. Problem description:
a. VMware HGFS File System Heap Overflow
The VMware Host Guest File System (HGFS) shared folders feature allows
users to transfer data between a guest operating system and the
non-virtualized host operating system that contains it.
A heap buffer overflow condition is present in VMware HGFS. Exploitation
of this flaw might allow an unprivileged guest process to execute code
in the context of the vmx process on the host.
In order to exploit this vulnerability, the VMware system must have
at least one folder shared. Two things must happen for a folder to
be shared. 1) Shared folders must be enabled, and 2) a folder must
be selected from the host system to be shared. No folders are shared
by default in any version of our products, which means this
vulnerability is not exploitable by default. Workstation 6.x,
Player 2.x, and ACE 2.x have shared folders disabled by default.
VMware Server, ESX and ESXi do not provide the shared folders feature.
Because there is no back-end for the HGFS protocol on the virtualization
host, these products are architecturally immune to this issue.
This issue might not be exploitable on host operating systems which
have implemented heap protection.
VMware would like to thank Andrew Honig of the Department of
Defense for reporting this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-2098 to this issue.

b. Windows based VMCI arbitrary code execution vulnerability
VMCI was introduced in VMware Workstation 6.0, VMware Player 2.0,
and VMware ACE 2.0. It is an experimental, optional feature
that allows virtual machines to communicate with one another.
With VMCI enabled a guest may execute arbitrary code in the context
of the vmx process on the host. This is a compiler dependent
vulnerability and only affects systems running on windows hosts.
VMware would like to thank Andrew Honig of the Department of
Defense for reporting this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-2099 to this issues.
