FINAL RESULTS:
data/python-udatetime-0.0.16/src/rfc3339.c:261:9: [2] (buffer) char:
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.
char fractions[7] = {0};
data/python-udatetime-0.0.16/src/rfc3339.c:484:5: [2] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf. Risk is low because the source has a constant maximum length.
