VMware ACE prior to 1.0.3 VMware ESX 3.0.1 without patches ESX-6856573, ESX-6431040, ESX-6704314, ESX-5095559. VMware ESX 3.0.0 without patches ESX-3496682, ESX-5754280, ESX-1256636, ESX-7104553. 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:

  1. 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 Rubén 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. http://taviso.decsystem.org/virtsec.pdf The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-1337 to 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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-1877 to this issue. ESX

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. Thanks to Ken Johnson for identifying this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-1876 to this issue. ESX

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. Hosted products
