Detailed Description
Business Impact:

These vulnerabilities allow an attacker to remotely execute code on the host operating system, which could be used to break out of the virtual machine. Although not trivial to construct, this attack is remote and requires no user interaction for success.

Once an attacker has control over the host operating system, additional attacks could be leveraged to compromise the entire virtual network.

CVSS: Base Score: 10
  Access Vector: Remote
Access Complexity: Low
Authentication: Not Required
Confidentiality Impact: Complete
Integrity Impact: Complete
Availability Impact: Complete
Impact Bias: Normal 
Adjusted Temporal Score: 7.4
  Exploitability: Unproven
Remediation Level: Official Fix
Report Confidence: Confirmed 
Affected Products: For a full list of affected versions, see references below.
Technical Description: The VMWare DHCP Server is vulnerable to an integer underflow and an overflow caused by improper bounds checking. By sending specially-crafted network data, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.
Remediation:

Patches are available for this issue. See References for details.
