DEPRECATED: Miscalculated Null Termination
This entry has been deprecated and merged into CWE-170 (Improper Null Termination). It was originally created as a duplicate, and all relevant information has been consolidated under CWE-170 for clearer vulnerability tracking.
CWE-132 was deprecated because it described the same core issue as CWE-170: problems arising when software incorrectly calculates buffer sizes or termination points for null-terminated strings. This often happens when developers manually manage string buffers without using safe functions, leading to off-by-one errors that can create non-terminated strings. These non-terminated strings then cause unexpected behavior when processed by functions that expect proper null termination. As a developer, you should now reference CWE-170 for comprehensive guidance on preventing null termination errors. Focus on using secure string handling functions from modern libraries, always validating buffer sizes, and avoiding manual character-by-character buffer manipulation. The consolidation into a single CWE entry helps streamline security education and ensures you're working with the most current and complete vulnerability information.
