DeleGate DNS Response Denial Of Service Vulnerability

DeleGate is prone to a remote denial-of-service vulnerability. This issue is due to a failure in the application to properly handle malformed DNS responses.

An attacker can exploit this issue to crash the affected service, effectively denying service to legitimate users.

The vendor has addressed this issue in versions 8.11.6 and 9.0.6; earlier versions are vulnerable.
