Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/python-prctl-1.7/_prctlmodule.c Examining data/python-prctl-1.7/securebits.h FINAL RESULTS: data/python-prctl-1.7/_prctlmodule.c:54:5: [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 name[17] = "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"; data/python-prctl-1.7/_prctlmodule.c:125:16: [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). if(strlen(argstr) > 16) { data/python-prctl-1.7/_prctlmodule.c:128:13: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy(name, argstr, 16); data/python-prctl-1.7/_prctlmodule.c:392:12: [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). ptr -= strlen(arg0); data/python-prctl-1.7/_prctlmodule.c:429:36: [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). len = (size_t)(argv[argc-1]) + strlen(argv[argc-1]) - (size_t)(argv[0]); data/python-prctl-1.7/_prctlmodule.c:430:5: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy(argv[0], title, len); data/python-prctl-1.7/_prctlmodule.c:431:8: [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). if(strlen(title) < len) data/python-prctl-1.7/_prctlmodule.c:432:26: [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). memset(argv[0] + strlen(title), 0, len - strlen(title)); data/python-prctl-1.7/_prctlmodule.c:432:50: [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). memset(argv[0] + strlen(title), 0, len - strlen(title)); ANALYSIS SUMMARY: Hits = 9 Lines analyzed = 798 in approximately 0.03 seconds (26854 lines/second) Physical Source Lines of Code (SLOC) = 705 Hits@level = [0] 0 [1] 8 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 9 [1+] 9 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 12.766 [1+] 12.766 [2+] 1.41844 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
