This service performs routing across the map information provided. A user shell is provided to allow input of map data, and route requests
The map supports roads, addresses, and intersections. Intersections are constucted by selecting two roads to join. Addresses are numbers on road, between two intersections. The map can be printed and routes from address to address can be resolved.
Routing is performed by traversing intersections on a discovered road to discover additional connected roads. As unique roads(nodes) are discovered, they are pushed to a list stored in a the data element of a linked list node. The size limit for the number of traversals which can be stored in the data element is checked against sizeof(pointer), rather than sizeof(element), resulting in a heap overwrite.
Different elements are stored in common data containers, creating a challenge for inferring data types. Also, a CRS must created a valid, sufficiently deep graph to reach the vulnerable route function.
