These kinds of flaw are regularly exploited by system crackers—serious stuff. It’s easy to avoid being bitten by these vulnerabilities: Don’t write such bad code! Use safer data structures that don’t allow you to corrupt the program—use a managed buffer like C++’s string class. Or systematically use 12 Chapter 1 safe operations on unsafe data types. The C code above can be secured by swapping strcpy for strncpy, a size-limited string copy operation: char *safer_copy(const char *source) { char *buffer = new char[10]; strncpy(buffer, source, 10); return buffer; } Check Every Return Value If a function returns a value, it does so for a reason.

It needs to read clearly to whoever might come back to it. This will include those auditing (code reviewing) the work you have done and anyone who maintains it later. Be kind to people who have to look after your code—just imagine yourself in their shoes.
