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/extlib-1.7.7/test/util/zlib-test/zlib-test.c FINAL RESULTS: data/extlib-1.7.7/test/util/zlib-test/zlib-test.c:15:14: [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. unsigned char dest[32]; data/extlib-1.7.7/test/util/zlib-test/zlib-test.c:32:51: [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. retval = compress2 (dest, &destLen, (unsigned char *)argv[2], strlen (argv[2]), level); data/extlib-1.7.7/test/util/zlib-test/zlib-test.c:32:67: [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). retval = compress2 (dest, &destLen, (unsigned char *)argv[2], strlen (argv[2]), level); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 43 in approximately 0.06 seconds (693 lines/second) Physical Source Lines of Code (SLOC) = 31 Hits@level = [0] 5 [1] 1 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 8 [1+] 3 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 258.065 [1+] 96.7742 [2+] 64.5161 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
