Preface: Essentially, any industry or application that requires communication in environments with unreliable or intermittent network conditions can benefit from BPv7’s capabilities. µD3TN has been successfully tested in Low Earth Orbit (LEO) on the OPS-SAT satellite, demonstrating its ability to handle the unique challenges of space communication, such as high latency and intermittent connectivity.

Background: The uD3TN project, a software implementation of the Delay-/Disruption-Tolerant Networking (DTN) Bundle Protocol, incorporates an allocator that functions similarly to the C standard library’s malloc dynamic memory allocator.

This allocator within uD3TN is responsible for managing memory allocation and deallocation for various components and data structures used within the DTN protocol stack. This includes, for example, the allocation of memory for bundles, which are the fundamental data units in DTN, as well as for internal structures and buffers required for bundle processing, forwarding, and storage.

The design of this allocator aims to provide efficient memory management within the constraints and requirements of a DTN implementation, potentially considering factors such as resource limitations in embedded systems or the need for robust handling of intermittent connectivity.

Vulnerability details: NULL Pointer Dereference in µD3TN via non-singleton destination Endpoint Identifier allows remote attacker to reliably cause DoS.
