WinGate DNS Compressed Name Pointer DoS
Medium Nessus Plugin ID 23732
SynopsisThe remote proxy is affected by a denial of service vulnerability.
DescriptionThe 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.
SolutionUpgrade to WinGate 6.2.0 or later.
