Technical details
An integer underflow vulnerability exists in the traffic parsing function of Absolute Security Secure Access clients prior to version 14.55. The flaw is triggered when the client processes specifically crafted tunnel protocol traffic. Exploitation requires the attacker to have intimate knowledge of and total control over the tunnel protocol, as well as user interaction. A successful exploit results in a non-persistent denial of service (DoS) against the affected client. The issue is addressed in client version 14.55.
