VMware ESX 2.5.4 prior to upgrade patch 8 (Build# 44671)
VMware ESX 2.5.3 prior to upgrade patch 11 (Build# 44672)
VMware ESX 2.1.3 prior to upgrade patch 6 (Build# 44407)
VMware ESX 2.0.2 prior to upgrade patch 6 (Build# 44406)
3. Problem description:
Problems addressed by these patches:
a. Denial-of-Service on Windows based guest operating systems.
Some VMware products managed memory in a way that failed to
gracefully handle some general protection faults (GPFs) in Windows
guest operating systems.
A malicious user could use this vulnerability to crash Windows
virtual machines. While this vulnerability could allow an
attacker to crash a virtual machine, we do not believe it was
possible to escalate privileges or escape virtual containment.
VMware thanks Ruben Santamarta of Reversemode for identifying and
reporting this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
assigned the name CVE-2007-1069 to this issue.

b. Denial-of-Service using ACPI I/O ports
Virtual machines can be put in various states of suspension, as
specified by the ACPI power management standard. When returning
from a sleep state (S2) to the run state (S0), the virtual machine
process (VMX) collects information about the last recorded running
state for the virtual machine. Under some circumstances, VMX read
state information from an incorrect memory location. This issue
could be used to complete a successful Denial-of-Service attack
where the virtual machine would need to be rebooted.
Thanks to Tavis Ormandy of Google for identifying this issue.

c. Denial-of-Service using malformed configuration data
Some VMware products support storing configuration information
files. Under some circumstances, a malicious user could instruct
the virtual machine process (VMX) to store malformed data, causing
an error. This error could enable a successful Denial-of-Service
attack on guest operating systems.
VMware would like to thank Per-Fredrik Pollnow and Mikael Janers
technical security consultants at SunGard iXsecurity.

d. Debugging local programs could create system instability
In a 64-bit Windows guest on a 64-bit host, debugging local
programs could create system instability. Using a debugger to step
into a syscall instruction may corrupt the virtual machine's
register context. This corruption produces unpredictable results
including corrupted stack pointers, kernel bugchecks, or vmware-vmx
process failures.

e. Directory traversal vulnerability in shared folders feature
Shared Folders is a feature that enables users of guest operating
systems to access a specified set of folders in the host's file
system. A vulnerability was identified by Greg MacManus of iDefense
Labs that could allow an attacker to write arbitrary content from a
guest system to arbitrary locations on the host system. In order to
exploit this vulnerability, the VMware system must have at least
one folder shared. Although the Shared Folder feature is enabled by
default, no folders are shared by default, which means this
vulnerability is not exploitable by default.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2007-1744 to this issue.
