Developing an appropriate fix for a software bug often requires a detailed examination of the code as well as generation of appropriate test cases. However, certain categories of bugs are usually easy to fix. This paper focuses on bugs that can be corrected with a one-line code change. As it turns out, one-line source code changes very often represent bug fixes. Careless use of file manipulation routines, failing to call free to deallocate a data structure, failing to use strncpy instead of strcpy for safer string manipulation, and using tainted character arrays as the format argument of fprintf calls are all well-known types of bugs that can typically be corrected with a one-line change of the program source.
