Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to an error when removing connections handled by a virtual server with an associated SOCKS profile from the connection table when the connections are finished. A remote attacker can consume all available connection resources and cause the system to be unable to process additional connections.
Successful exploitation of the vulnerability results in denial of service.
Mitigation
Install update from vendor's website.
