Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.

Check when opening files - can an attacker redirect it (via symlinks),
force the opening of special file type (e.g., device files), move things
around to create a race condition, control its ancestors, or change its
contents? (CWE-362).

Unless checked, the resulting number can exceed the expected range
(CWE-190). If source untrusted, check both minimum and maximum, even if the
input had no minus sign (large numbers can roll over into negative number;
consider saving to an unsigned value if that is intended).

Function does not check the second iterator for over-read conditions
(CWE-126). This function is often discouraged by most C++ coding standards

overflowing it.
