FINAL RESULTS:
data/python-geotiepoints-1.2.0/geotiepoints/multilinear_cython.c:757:5: [4] (buffer) strcpy:
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).
strcpy(__PYX_DEFAULT_STRING_ENCODING, default_encoding_c);
data/python-geotiepoints-1.2.0/geotiepoints/multilinear_cython.c:26417:5: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.

This function is not sufficiently random for security-related functions
such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.
