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/yajl-tcl-1.7.0/generic/tclyajltcl.c Examining data/yajl-tcl-1.7.0/generic/yajltcl.c Examining data/yajl-tcl-1.7.0/generic/yajltcl.h Examining data/yajl-tcl-1.7.0/generic/yajltcllex.c Examining data/yajl-tcl-1.7.0/generic/yajltcllex.h FINAL RESULTS: data/yajl-tcl-1.7.0/generic/yajltcl.c:332:5: [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 str[16]; data/yajl-tcl-1.7.0/generic/yajltcl.c:1121:13: [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 argString[32]; data/yajl-tcl-1.7.0/generic/yajltcl.c:1125:13: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf (argString, "%d", arg); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 1671 in approximately 0.06 seconds (27777 lines/second) Physical Source Lines of Code (SLOC) = 1065 Hits@level = [0] 3 [1] 0 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 6 [1+] 3 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 5.6338 [1+] 2.8169 [2+] 2.8169 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
