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/potool-0.19/common.h Examining data/potool-0.19/i18n.h Examining data/potool-0.19/po-gram.h Examining data/potool-0.19/potool.c FINAL RESULTS: data/potool-0.19/potool.c:348:8: [4] (format) vprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. ret = vprintf(format, ap); data/potool-0.19/potool.c:652:14: [3] (buffer) getopt: Some older implementations do not protect against internal buffer overflows (CWE-120, CWE-20). Check implementation on installation, or limit the size of all string inputs. while ((c = getopt (argc, argv, "f:n:scph")) != EOF) { data/potool-0.19/potool.c:62:2: [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(ret->line_lengths, block->line_lengths, sizeof(int) * ret->num_lines); data/potool-0.19/potool.c:377:9: [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). slen = strlen (s->str); data/potool-0.19/potool.c:386:15: [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). prefix_len = strlen (prefix); data/potool-0.19/potool.c:444:19: [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). int prefix_len = strlen(prefix); ANALYSIS SUMMARY: Hits = 6 Lines analyzed = 857 in approximately 0.04 seconds (23553 lines/second) Physical Source Lines of Code (SLOC) = 718 Hits@level = [0] 1 [1] 3 [2] 1 [3] 1 [4] 1 [5] 0 Hits@level+ = [0+] 7 [1+] 6 [2+] 3 [3+] 2 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 9.7493 [1+] 8.35655 [2+] 4.17827 [3+] 2.78552 [4+] 1.39276 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
