Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/python-scandir-1.10.0/_scandir.c Examining data/python-scandir-1.10.0/osdefs.h Examining data/python-scandir-1.10.0/winreparse.h FINAL RESULTS: data/python-scandir-1.10.0/_scandir.c:1378:5: [4] (buffer) wcscpy: Does not check for buffer overflows when copying to destination [MS-banned] (CWE-120). Consider using a function version that stops copying at the end of the buffer. wcscpy(result, path_wide); data/python-scandir-1.10.0/_scandir.c:1383:9: [4] (buffer) wcscpy: Does not check for buffer overflows when copying to destination [MS-banned] (CWE-120).
