Detecting Dangling Pointers Using Embedded Metadata, Kentaro Hara, Benoît Lizé

Defensive Publications Series

When the memory for an object is deallocated, pointers to that object become invalid. Such pointers, known as dangling pointers, can be exploited by attackers to cause undesirable or malicious program behavior. A pointer that points to memory that has been reused (reallocated) is known as a use-after-free pointer; these, too, are gateways to exploits. This disclosure describes techniques to detect the presence of dangling and use-after-free pointers in runtime and, upon detection, forestall security breaches due to such pointers by causing a program crash accompanied by a bug report. Per the techniques, both pointer and pointed-to object are augmented …

Proximity-Based Triggering Of Screen Restrictions To Avoid Eye Strain, Eric Liu

Defensive Publications Series

Viewing device screens in close proximity can cause eye strain. Some devices use front-facing cameras to detect and recognize faces in order to personalize the user experience (UX) to the user close to the device. However, such personalized operation does not include functionality that depends on the user’s proximity to the device screen. Proximity sensing within devices is used to turn the screen off in situations when the device is held against the user’s head. Such capacitive proximity sensing operates at distances from the screen that are relatively short. This disclosure describes techniques to change the operation of a device …

Corrosion Of Coated And Uncoated Steel Reinforcement In Concrete, Jana Abou Shakra, Rouba Joumblat, Jamal Khatib, Adel Elkordi

BAU Journal - Science and Technology

Corrosion of reinforcing steel is the one of the main causes of deterioration in reinforced concrete structure. During the initial stage of corrosion, the steel volume increases. This creates tensile stresses in the concrete, which can eventually lead to cracking, delamination, and spalling. This potential risk of corrosion in a structure is quite unpredictable. Therefore, this paper examines the influence of accelerated corrosion on the bond between concrete and the coated and uncoated steel bars. The bar coating consisted of epoxy rich in zinc. Six concrete mixes were prepared. Three mixes had cement contents of 300, 400 and 500 Kg/m3 …
