WinGate Compressed Name Pointer Denial of Service Vulnerability

Vulnerability Assessment Summary
Checks version number in WinGate's banner

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote proxy is affected by a denial of service vulnerability.

Description :

The remote host appears to be running WinGate, a Windows application
for managing and securing Internet access.

The version of WinGate installed on the remote host contains a flaw
involving the processing of DNS requests with compressed name
pointers. By sending a specially-crafted DNS request to a UDP port on
which WinGate is listening, an unauthenticated remote attacker can
cause the affected application to consume 100% of the available CPU,
thereby denying service to legitimate users.
