Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Passing the wrong data type to a function is most common in loosely typed languages and with implicit casts. Here is what CWE-686 means and how to guard against it.
Passing too many or too few arguments leads to undefined behavior, especially in C and Perl. CWE-685 explained with an example and simple checks.
When code does not behave as its documentation says, callers build on a false promise. CWE-684 covers signature checks that say OK when they should not.
Swapping two arguments is easy to do and easy to miss when the types match. CWE-683 shows how it can bypass access checks and how to catch it.
A wrong offset, a wrong width or a wrong comparison can break allocation, permissions and certificate checks. CWE-682 explained, with fixes.
Casting a long to an int or a signed value to unsigned can quietly change the number. CWE-681 is what happens when that wrong number reaches an allocation or a security check.
When a size calculation overflows, malloc hands back a tiny buffer and the next copy runs far past it. Here is how CWE-680 works and how to guard the arithmetic.
Some C and C++ functions are safe only if every caller gets every detail right. CWE-676 covers using them anyway, and how to ban them from your codebase.
Closing a file twice, unlocking twice or decoding twice can corrupt state or bypass filters. See the cases MITRE lists and how to guarantee single use.
