Prof. Maria Damiani gave a talk on “Spatio-temporal access control: state-of-the-art and open issues”. Abstract In the last few years, a number of spatial and spatio-temporal access control models have been developed in the framework of pervasive computing and location-based services. The distinguishing feature of those models is… Read More
Prof. Daniel S. Yeung gave a talk on “Sensitivity Based Generalization Error for Supervised Learning Problem with Applications in Model Selection and Feature Selection”. Abstract Generalization error model provides a theoretical support for a classifier’s performance in terms of prediction accuracy. However, existing models give very loose error bounds. Read More
Together with sipgate and ISMK Stralsund, Gabriel Gegenhuber, researcher at SBA Research and University of Vienna, and Michael Pucher, researcher at SBA research, discovered and investigated a vulnerability in the Voice of LTE (VoLTE) stack that is broadly used within MediaTek-based smartphones. ∞
In the Mediatek modem, there is a possible system crash due to a missing bounds check. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. ∞
