WebUndefined behavior may also cause buffer overflow attack, if for example an array out of bounds is not checked. The advantage of undefined behavior in C is that the program avoids the unnecessary checking (such as arrays out of bounds), that results into better performance. C99 international standard presents a list of 191 undefined behavior cases. WebOr does one need to use an external tool, and if so which tools could detect this and do these detect all undefined behavior or only some specific cases? Related Topics .
