Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).

Does not check for buffer overflows when concatenating to destination
[MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
snprintf (warning: strncat is easily misused).

if available.

around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
