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).

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.

Potential for temporary file vulnerability in some circumstances. Some
older Unix-like systems create temp files with permission to write by all
by default, so be sure to set the umask to override this. Also, some older
Unix systems might fail to use O_EXCL when opening the file, so make sure
that O_EXCL is used by the library (CWE-377).
