Space Patch Information

Description

The Portable Space Code has provision for a number of separate universes. There is a constant, SPACE_LIMIT, defined in the spaceconf.h file. This value is used to directly initialise the array used for each space.

Unfortunately, there are a number of places SPACE_LIMIT is incorrectly checked, and where it is possible to access data beyond the allocated space. (A number of checks are made for > SPACE_LIMIT, where the correct check is >= SPACE_LIMIT)

This patch corrects these limit checks, and so prevents an out of bounds pointer from crashing the engine.

Installation Notes
