FINAL RESULTS:
data/libgnatcoll-python-21.0.0/python/python_support.c:177:4: [4] (buffer) strcat:
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).
strcat (command, name);
data/libgnatcoll-python-21.0.0/python3/python_support.c:155:4: [4] (buffer) strcat:
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).
strcat (command, name);
data/libgnatcoll-python-21.0.0/python/python_support.c:78:4: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(module, &def, sizeof(struct PyModuleDef));
data/libgnatcoll-python-21.0.0/python/python_support.c:176:4: [2] (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). Risk is low because the source is a constant string.
strcpy (command, "import ");
data/libgnatcoll-python-21.0.0/python/python_support.c:252:5: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy (&PyAdaMethodDescr_Type, &PyMethodDescr_Type, sizeof (PyTypeObject));
data/libgnatcoll-python-21.0.0/python/python_support.c:315:11: [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.
static char msg[200];
data/libgnatcoll-python-21.0.0/python3/python_support.c:69:4: [2] (buffer) memcpy:

data/libgnatcoll-python-21.0.0/python/python_support.c:175:38: [1] (buffer) strlen:
Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
char* command = (char*)malloc(9 + strlen(name));
data/libgnatcoll-python-21.0.0/python/python_support.c:178:4: [1] (buffer) strcat:
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). Risk is low because the
source is a constant character.
